General Principles of Foundational Sciences

Good explaination, Love it! Easy to Understand, Keep it up!

Simple and easy going explaination! easy for me to understand. Keep it Up!

Explica las cosas super simples y puntuales, se memoriza rapido de esa manera

she reads from her notes too much, strikes me as someone who does not have a firm grasp on what she is teaching.

I think it’s too fast, and not with details so please correct these problems

Magnificent lecture about polysaccharides and their functions for storage and release

Very clear and succinct. May have gone a bit too fast, but that's always manageable

The video highlights the important concepts about the hydrophobic amino acids group

This lecture was great! I could understand what the professor was explaining and I understood it pretty well.

I recommend include the cc out of slides screen, the letters do not allow to watch the information

The lectures are very thorough and give good details about what is high yield.

I love the way he explained enzyme.... A brief and easy to understand lecture

Very interesting and engaging. The energy from Dr. Racaniello is absolutely contagious, thank you very much!

Basic topics which i had difficulties in understanding has been well explained and now I have fixed the knowledge :) Suggestion: it's hard to cover the extremely fast growing biotechnology topic but I guess "omics" would be good to add

Thank you Dr. Kevin Ahern. You made me fall in love with biochemistry.

I haven't reviewed the lecture but personally from watching some of the previous vids I feel that doc Vincent is not giving a USMLE lecture. while what he does is very good, lecturio is very specific for USMLE, the lecturer has to hit the most high yield points in the most concise and easy to understand way. the benchmark would be Hassan sattar in pathoma, very on the point summarizing massive topics to a single slide.

Definitely enjoyed this lecture. Concepts were concise making it really easy to follow. I enjoyed actually practicing the case study questions as it tested my understanding of the topic

I really liked the explanation, finally after 2 years, I understand this!! Thanks :)

I like the way you explained how this signaling process work

It is really concise. He did a good job pointed out the importance of Aquaporin-2 in the body (specially in the kidney) and why we should care.

I always enjoyed Dr Ahern's handling of the Biochemistry subject, especially his eplanations

I really liked it and enjoyed Dr Cornwall'ss explanation. The only issue was that the video slowed at some point.

Despite the mishaps, I thought the information was understandable. Especially the ending when she connected Trp and Lac operons with repressible and inducible.

I like how much simple he makes the tough materials in pharmacology course

It's is just good that's why 4. I dislike that it's doesn't explain clinical too much

It's okay.... But somehow hard to comprehend. I will love if you can make the teaching much easier to grasp.

Most of it was good and understandable but towards the end, it became quite confusing to follow along.

Every slide has been clearly explained in detailed form. Thanks sir.

It's unfathomable how much this lecture has saved my time. Though I would appreciate a quick-summary of the products turning into intermediates for other cycles. Like with how g-1-p turns into g-6-p

I saw many times the video, take notes but I don't understand at all this video; think is some confusing :(

The lecture simplified glycogenesis to extreme simplicity. It truly helped save around 30 minutes from my lecture, by providing adequate information

Hi I appretiate her lectures about biochemistry, l hope the following lectures would offer me more interesting information.

Too fast and sometimes lacking pretty basic, though essential details about the whole process.

This lecture is very informative yet concise. Everything that you need to know is here. Thank you

Excellent, clear, interesting and informative presentation which facilitates comprehension and memory of essential material.

lecturer is breathing heavily that is kind of distracting. I don't know if it is because she is wearing the mic very close. lessons were nice tho.

this is amazing thank you , i gained a lot of info about viruses that i have not know before

I am in my first semester of Bachelor of Science in Biomedicine in Switzerland and the courses are helping me a lot. I can watch your videos after a whole day of studying and I am always having fun! I get a great overview and know what the most important concepts are. I also have no issues remembering what I learn here. Thanks a lot! I learn new things while answering the quiz questions as well, they are smartly structured and help a lot as well.

A great source at this time, I totally would recommend to my colleagues.

very clear explanations and the questions helped me understand the content

Love your lectures, Professor. It is helping me a lot reviewing Biology as It's been years since my basic science years.

this is a good lecture i really understand a lot of thing i haven't know before tysm

Although the whole course (and actually the whole of Lecturio) is absolutely wonderful, I enjoyed this lecture with Dr. Cornwall so thoroughly, that it felt like time was passing by rapidly! Before I knew it, the lecture was over and I had learned so much! Dr. Cornwall has a way of explaining things that makes you understand is the matter longterm and makes you curious to look deeper into it. Thank you very much for everything! Eileen Dara Greetings from Belgium

simply explained so well understood, very well done. lots of info but concise

Very good introduction courses for beginners and much knowledge for course reviewers!

I select leturio because its teaching method is very awesome knowledge base Usmle type based

i understand it though, you just need to concentrate on what the prof is saying and correlate well with the diagram then youll understand

Me gusta mucho el contenido que he recibido por parte de este curso, porque la información me parece clara y precisa. Además me agradan los ejemplos que se usan para el tema.

I like it becauser it was very helpful & simple .. I like the translate sevice it so helpful as well. Thanks a lot lecturio

It's good, informative not as detailed as I need it to be but it's a good framework to build on

Great concise videos covering salient points in biotech. Most of material is well presented though some concepts I've had to supplement with other sources to fully understand. Overall, great useful series. Thank-you Dr. Cornwall!

It is a good introduction for the following classes. It's not confusing, but more information could be added

Clear and concise. well-explained, clear diagrams, builds on my existing knowledge

Liked it too much as it's so easy to understand ????...but cannot afford premium ????

this video is short and easy to understand. Thanks Teacher

Good explanation. Pretty bad diagram. Animation probably would work better.

Hello Professor Ward. M1 student from CA here. I just wanted to say that I think these lectures are super awesome, and thank you for taking the time for ensuring good quality while also making great responses to student questions.

First of all, I like the depth of this lecture and Professor Ahern is clearly very knowledgeable and concise on the the topic being discussed. And I also like due to the fact that this video is clearly a high-yield resource which is very helpful for my upcoming medical exam. However, I believe that this could have been better had the previous cycles preceding the formation of OMP explained as well in order for us the students to be able to get the essence of the information better. That's all I have got to say

Dr. Cornwall is awesome! Her lecture are clear and concise. She makes the material so much more digestible.

Dr. Cornwall is fantastic! The biotechnology series helped me SO MUCH going into lecture.

She keeps it short and simple. Great work in this video. It's great prep before going into a lecture!

Me encantan las clases son muy explicativas y muy detalladas , simplemente excelente!!!

Excellent Lecture from lecturio; I highly recommended for students from medical school. It is an excellent learning platform.

i enjoyed every second of this video and it opened my mind to study more and become what i have always wanted to be a radiologist

I love lecturio, it's the best app in the world. Lecturio has everything you want and can help you to be the best in your class and also be the doctor you want. Lecturio is an opportunity that can give you the change of your student life.

Concise and clear; exactly what I needed for this topic, thank you.

Good amount of detail in digestable amounts. Very much appreciate able to run the videos at different speeds.

No explanation at all just reading , sorry for that , No interaction

Very good review .enjoyed the enthusiasm. Visuals were ok but not really understood.!

It's great to learn from someone who's enthuisiastic about their specialty and even better at teaching it. Thank you Dr. Ahern (:

the course lectures were wealthy in information although they are short which made me interested in completing the course

the tone of voice and eye contact good just like in a classroom

This lecture is amazing and I loved the explanation regarding the conformational change of hexocinase during the reaction.

His explanations are very good. Biochemistry made easy!! He is very good in teaching.

beautifuly explained. thankyou!! Every point in every step was explained nicely.

Interesting and informative! Expounded well on complex concepts and gave a riveting lecture.

I like the short videos. They described what’s important and later you get questions about the video.

Both lecturers are very clear and Dr Elliot goes slowly so I get more of the quizzes correct.

TOO SIMPLIFIED AND IT SEEMS LIKE THE LECTURER WASN'T WELL-PREPARED FOR THE LECTURE KEEP SAYING NONSENSICAL WORDS. I AM REALLY FURIOUS AND FRUSTRATED LISTENING TO HER LECTURE.

Me agrada como explica las cosas la Dra, creo que lo hace que sea entendible de forma sencilla para cualquiera

Pretty well explained. Its short and very useful when i have to study for my college tests. Totally recommended!

The lecturer speaks clearly and is engaging. The material is presented quite well - in a logical manner. I feel the material could go in a bit more depth (but perhaps later lectures will). I would probably give this series 5 stars, however, I'm currently studying for the USMLE, and I feel half or more of the review questions are extremely low-yield. For example, there are questions about which section of a plant does a specific fungus infect. That's okay to test understanding of the lecture material presented, but I don't want to have that type of question included in my "Spaced Repetition" for memorization. It's a real waste of my limited time and brain space. Please ither remove the low-yield questions, or perhaps a better (and faster) option would be to add an option to turn off the "dumb" questions.

La Dra explica muy bien y de manera sencilla, algo que me gustó mucho son las analogías que utiliza para dejar claras las cosas, creo que eso lo facilita

Love the course, thank you very much teacher, it really helped me.

Reviewing for my NP certification and this is an excellent resource.

I belive she is very clear and resume complicated topics nicely.

So easy to learn, this classes need more diffusion, thank you.

I love the course, it's easy to learn and to understand

This course has all I need, so a 4 star. However, I didn't get something special so not 5 star.

I find embryology confusing and this video really helped me out, thank you

I suppose it depends on your learning style. That is, most of the medical students I've spoken to, appreciate concise and coherent lectures - Unfortunately, in my personal opinion, this micro-lecture lacked the fundamental high concentration of information that most of us are looking for - to take notes, and practice the spaced repetition model. Instead, her speaking pace, and vocal expression are slightly too fast and the way in which she attempts to outline a basic idea isn't linear in nature which leads the viewer wanting to know more, while simultaneously trying to ignore the off-topic rants. Note: Clearly, she's qualified to teach - however, valid of a point that may be, doesn't mean she has the practical communication skills to do so. Therefore, this is not a question of intelligence, rather - communication and linguistic expression. There will certainly people who prefer this method, I however, can not recommend.

I had many doubts but with the lection, I improved much better

The lectures seem to cover all the necessary contents, but it’s often difficult to understand the topic until I go over the video again for several times.

I love having access to such rich learning material, thanks for making this an available resource. My only criticism would be that the quiz questions could use improvement and the professor could talk slower to make note taking easier. Overall, very grateful to have found this!

This lecture clearly points out the differences between prokaryotic and eukaryotic cells in protein synthesis. It would be helpful for those who wish to briefly know how proteins are formed in each type of cell.

It is a good explanation for a complex topic, with only the most important

I spent weeks reading and trying to understand from the books but these lectures made it so easy to understand, I also love the fact that it keeps on asking questions so you can remember them. Thank you so much for these lectures, I love them.

Teacher speak slowly to help me understand Glucose in my body

rate of speech is good and i understanded the subject he explains it very simple

me gusto muchísimo lo recomiendo a todo el mundo que quiera saber mas

complicated topic but I think I got it, though the Tyrosine kinase itself is a bit complex

I like the format - the lectures are "short and sweet". The lecturer is reasonable easy to listen to. Perhaps it is just because this is a foundation course, but it does feel this material may not be in-depth enough for USMLE step 1. (Or perhaps because it's re-used for non-USMLE students?). The questions are just "okay". There are a few errors, and a couple questions could be worded better. It also seems that some of these questions are testing material that seems only marginally important, and may not be very "high-yield". I wish there was an option to flag review questions to not be included in the "spaced repetition". The "spaced repetition" idea should be for memorizing the most important details, and I don't really want to be memorizing questions that I think are of little importance, incorrect, or poorly worded. (It'd also be a good way your you at Lecturio to decide which questions should be revised - if many people flag it as "don't review again", the question probably needs revision.)

not clear voice . . . . . . . . . . comparatively worse than other videos, others are good.

Understandable!!! Easy to remember! And pretty useful!!! You really need to learn basics topics in Med career it surely make you to be highlighted over another students

Clear and precise explanation! Goes into the essence of this condition and correlates very well the clinical presentation

It helped me clarify some topics I had been having trouble with.

Sorry, the following videos have the information that I was looking for, sorry again

Amazing way of teaching, compact and efficient. Really good job, keep doing it Mr. Ahern.

well explained very scientific simply explained good writing onscreen good tone of voice expression

Has high yield infos which are not in other lecturer's lectures

As I stated in prior lessons, Dr. Cornwall is such of an amazing instructor!!! She makes easy to understand heavy contents

I would like to inform you that from 3:54 onwards there is neither the transcription nor the translation in other languages. I hope you will solve it as soon as possible because some concepts I cannot translate from English into Italian. Thank you in advance

the instructor is very clear and is easy to follow

Dr. Cornwall did a very great job with this.. The big picture simplified everything and made studying into little details easy.

very didactic I really enjoy Dr. Cornwall lectures, definitely Lecturio was the best addition to my preparation

el contenido esta muy bueno, solo que la traducción tiene falencias y dificulta entender los conceptos adecuadamente.

Everything is confusing. The diagrams and what she was saying didnt allign. ALso she never gave the answer to the number of chromosomes in each stage of meiosis and mitosis

I really like the video, makes medical biochemistry easier to understand

I liked the analogy of the gnomes in order to remember what are the causes of acid base disorders.

I've taken classes from Dr. Racaniello previously on the coursera.org platform. He is a very engaging instructor and he is no different in this Lecturi series, at least for the free part. As a citizen scientist, the full cost is too much so for this series I can only comment on the bacteria sections that are free. The quiz questions are very relevant to the material presented and the reference material is equally good.

Excellent, really like the Acid-Base box method and will definitely incorporate that into my exam technique and eventual future practice!

My professors at university failed to explain lipid metabolism in an understandable manner. Prof Ahern does a great job in explaining complex topics and I am really grateful for that. Thank you

I would recommend the Dr. Georgina Cornwall to look more towards the camera.

Well explained and easy to understand the concept. I'm on the right track and enjoying the course.

So nice and well explained with great doctors ???? they make the impossible possible

the explanation is complicated it could be simplified more better

It was fun learning the content. Frankness was encouraging. Important points have been outlined

Its apt for 2nd yrs....simple and all main points are given.

I loved it, really interesting and easy to comprehend, thank you very much :)

Very well taught, good refresher. The high yield points are in there too.

Very well explained. Would have appreciated had the lecture been a bit more comprehensive on certain topics, like in DNA replication and also a dynamic step by step diagram of the process would have been better to understand.

Need more mcq 's for practice and good content. Very clear concept s

The lectures are great... But I just feel like they are too expansive... Not very suitable for a dedicated study period

Both Dr. Sean Elliot and Vincent Racaniello are awesome. Both of them provide key information of microbiology. The presentations are clear and easy to remember

Loved it . High yield and to the point the lecturer was very clear and the quiz at the end of the lectures were very helpful

Very good Thanks Really it doesn't take much time and its really good

El programa ya se me acaba en dos meses, estaría muy interesada de volver a comprar si tuviesen en español y tambien como estudiante me ayudaría mucho un descuento

I really liked all the lectures They are to the point

the lecrure is detailed and very comprehensive it is well presented i also liked the quiz that comes afer the lecure.

i chose this rating because the lecture is up to the minute, well researched. and the presentation is straight to the point.

Excellent breakdown of key topics and very easy to follow.

J'ai adoré les cours ,ils m'ont économisé beaucoup de temps de révision ?

The classes are short covering usually one topic at a time. This allows more to learn the material easily.

It almost always fails to explain 'why'. These lists are available in any textbook. I was looking for an explanation to understand it. Also, visually it is looking at a table for 5 minutes, pictures could have explained better.

Before Lecturio I struggled with comprehending the mechanism of proteases and enzyme kinetics. Dr. Ahern brilliantly & easily explained these concepts in less than 5 minutes. I am currently in a graduate program for Medical Sciences, we have cumulative exams every quarter & I was just memorizing the info but now I finally understand. I recommend Lecturio to pre-meds, MCAT, and Med students.

Kevin sir explanation is very very nice and it's an extraordinary talent and explanation but little more information should be presented in power point slides so that we can learn more and more by step by step .. Thank you sir From Sanjeev India

Dear sir/madam In regard to the Biochemistry basics,I am much satisfied by the cours.In fact,the videos concerning biochemitry basics are well summarized and are full of useful information in the regard of médical studies.Because of this,I am enjoying the course and continuing either to learn much more . Yours sincerely Asher Hategekamungu

Excellent lectures. Racaniello is very concise, knowledgeable and interesting. Visuals in lectures good too. Pace is at optimum speed and duration of each lecture in a nice digestible package. Content is of adequate depth - not too simplistic and not too complicated. Sequencing seems to be a little off though, with questions appearing before video. First virus video seems to talk about Baltimore classification as if already covered, so I’m not sure if sequencing of videos is correct either.

He is so natural , after topic explanation he then takes example of daily life, easy to understand

the explanations provided for each disorder weren't very thorough nor well explained

This is a great overview of CYP and PGP issues. Drug biotransformation is a very complex topic and this is an excellent primer on some key issues. I hope to see more like this.

Dr. Ahern is a fantastic lecturer. All the course is simply awsome.

Dr. Ahern is a fantastic lecturer. All the course is simply awsome.

It is very concise but it provides enough information. I am very satisfied with Lecturio because this course and Biochemistry are exactly what i was looking for.

The video episodes are way too short, need to go back and start over every 3-4 minutes. I think there should be a option to view the topic in one full video. Otherwise the subjects are well covered in an understandable manner. Many thanks

It gave me all the information I needed. Plus the videos were updated to COVID-19. I definitely recommend this to all health care workers

Complete lessons and amazing teacher, I’m learning a lot from this course

The way of teaching of Georgina is really impresive, i understanded everything. The best classes ever.

The course was easy to follow and has good illustrations of the concepts. I also like the quiz portion of the course.

Very comprehensive lecture . It' s clear and simple. Thank you for your work .

The ease of listening and staying engaged is incredible...there's a lot of information, but before you know it, you've completed the lectures. The real-world approach makes it easy to focus, I appreciate it. Thanks

I liked that the subject was covered in depth and was easy to understand. Good for clinicians and med students.

Interesting and informative across the spectrum. This course covers everything of interest.

Great courses ,knowledgeable and passionate professors.Perfect for those who will forever have a thirst for knowledge. I wish there were more hours in the day

Hands-on experience on a plate of gold, much appreciated. Looking for more videos like this in the future

this presentation was good and the way sir explained the concepts was nice

Great Great great great great great great great great great

Excellent teacher, excellent images and the technique explication is amazing

Great professor and easy biochemistry topics to learn with good explanation.

O really like it , because the lectures are very clear. And I understand everyrhing.

This video is gets straight to the point and is very informative.

It is a good way to learn about Acid-base balance

I work in a large public hospital biochemistry routine department, when I studied this subject there where no computers, only text books. So this is a refresher and update of the subject. I am enjoying this 'new' way of learning and it enhances my work knowledge as understanding theory is important for performing work well.

difficult subjects are explained by simple words by Georgina. Thanks so much!

Whenever I get confused about a pathway, I come to watch these videos and it helps tremendously. Thank you for what you do.

Covered all high yield points , very nice illustration which helps in remembering things better

I found these lectures very interesting and very useful! Congratulations to the ability of communication of the teacher.

MA SHA ALLAH.. It was great and easy to understand I am glad

Ggghh hhjj hjkkllj jjkpppo hjk hjkk hukkk huiook hhjkk hhjjj jkkkkk uikkkkkk hkkkj

I recommend everyone to Follow the 100 Day Study Plan given in Lecturio App. Its Amazing.

Very insightful and helpful for doctors on the frontline. Thank you.

Summarised but enough to have good knowledge about Fungi, its recommended

Excellent and well presented lectures ,easy to understand and refresh memory!

sorry to say it is really not well explained or concept clearing kindly modify lecture

Very clean and understandable lecture with charts and perfect voice of the lecture

VERY clear explanation of how this works, I love Ahern's lectures.

good information .... in this moment we must know the actual situation at the world

Me ayudan como introduccion al tema, y me orientan que aspectos son importantes resaltar, me gustó los tips para recordar temas importantes no me gusto que duran muy poco y abarcan muy poco sobre los temas, estaria bueno que dieran mas clase , mas explicacion, la mayoria son casi menos de 5 minutos. aun no he provado la version premium , pero ese aspecto de poco tiempo no me convence del todo.

hi first of all she is talking very will as good speaker and the explanation in different lecture was so systematic and will prepared and hit the main points that I'm really interested to her course of biology.

As a senior medical student about to graduate and join the healthcare workforce as a general practitioner in the midst of the COVID-19 pandemic, I can count on Lecturio for providing high yield, practice-enhancing information. I am actually impressed by how quickly Lecturio did put together and deliver this evidence-based and up-to-date course. Dr. Elliott is a great teacher and his contribution to this video is likely to end up having a significant impact on COVID-19 patient management throughout the world. Also, thank you for making all content related to COVID-19 free for everyone including non-members. I intend to share this course and/or Lecturio's COVID-19 concept card with my professional network on LinkedIn (https://www.linkedin.com/in/jfechelard/). Stay safe. Jean-François Echelard

It’s valuable and well presented lectures ! I recommend it for my colleagues

very helpful thank you for this info , hope to continue and update

It is an xcellent explication! I understend it at all. Thank you

es un excelente vídeo, y esta muy bien explicado; justo el tema de mi próxima evaluación

I am from Peru, and Dr. Wilson's class seemed very good to me, very concise and the key points incredible, very satisfied with the presentation.

She explains good and the material is authentic. It is helping me alot, since I was hospitalised in my recent classes.

Great lecture! Very simplified and friendly explained. Thanks so much !

This is completely inadequate for the questions posed. The first question gives "you observed red gnomes outside the box on the left for both pH and HCO3" and asks for the condition. Verbatim from the lecture ‘’Respiratory alkalosis’’. Why? Cos there are two gnomes on one side." Yet the answer is metabolic acidosis.

It was vvvv nice thanks Nicely explained and easy to recall

Ok. Very good excellent benefits i love it so much it is so good

It was very comprehensive and interesting. I want to become a virologist too.

I always had problems understanding this topic and I always got confused, especially with the last big summarizing diagram. However, this whole lecture helped me to get through it, therefore I can not be thankful enough.

Each RNA should be shown in the picture like above

Really liking the microbio bacteria videos. Feel like the presentation of the info is well done and really easy to grasp in such a short amount of time.

I like his style and respect his effort. I've been using these lecturers to review my knowledge

This video is precise and concise, thanks a lot, I found this series to be incredibly helpful

It is a good course but the content here is not really high yield.Do we need to spend so much time on it?

the way he explains , dat is funny. I see some nerds didnt like the lecture, meh get a life "nerds" :D

Interesting and relevant overview of fundamental concepts related to aging and some high yield diseases seen in geriatrics. Thank you Dr. Cornwall for sharing your immense knowledge with us in this course.

Very clear and useful for me to finally get a grip on this topic.

Microbiology is explained very clearly in a interesting manner its no doubt an interactive method of teaching!!!

Brings together a balanced and complete picture of the usefulness and pathologies caused microorganisms.

i can't understand why a lot of amazing videos have 1star points

I find the teaching style to be effective and well planned. I use lecturio for supplimenting the topics taught in my classes

Excellent teaching communicating principles and important details at perfect pace.

Dr. Cornwall makes the topics easy to understand and retain. Her approach is not overwhelming but yet not so simple you are bored.

The lecturer tripping up make it a little difficult to follow but it is made clear in the end.

Talking about things that aren't on the slide https://www.ratemyprofessors.com/ShowRatings.jsp?tid=833581

Good course but we need more practice on the problems

Extremely informative and engaging. Amazing lecturer! Thank you! You make concepts so clear, and provide real-life scenarios for the diseases caused by the microbes. Humourous in some places, which makes the content easy to remember.

Very detailed. Moves through information and a good pace. Sifts out the important information versus stuff we don't need to know for the exam.

the concepts are clear and the time is enough, examples are short.

Very insightful and brilliant explanation. I learned very much in this lecture! School professor just skip much of the importance in PPP!

hi Biochemistry's videos are interesting and give me information, the orator pronounce correctly. As you know I do my best to prepare ecfmg exam and board examination next, of course after having sufficiently training and advices under your guidance I would like to apply ecfmg examination this year, now would you please give me more information for preparing step one and step 2 exam.

So much better explanation than our school professor! I really appreciate the way Dr.Raj teaches. Recall the basic biochemistry and then deep into the pathology.

Very informative. Well presented in an easy to understand format.

This is incredibly difficult to follow with the lecturer mis-speaking constantly

the reason chooses this rating regarding pop up AD, I am not ready yet. I need more time to think about what my work schedule to fit my study and payments.

Excellent, clear, didactic presentation of the basics of membrane physiology.

??? ???? ?? ??? ?? ??? ??? ???? ??? ?? ?? ??? ?? ??? ???

I believe the term is entropy is misused in this lecture.

I have learned a lot through her lectures, I love her lectures, she explains things very well.

A very witty doctor. Im learning enjoying at the same time

Excellent lecture, well explained so I could understand it. So important to understand and not just memorize these topics.

Excellent lecture. Understood Bohr effect better than ever. I love these lectures.

Most of us studying at this point (USMLE Prep) know this stuff well, however; this does provide a good refresher to get the juices flowing in the right direction while studying for the boards.

Misuse of the words fludity and stability as if they were synonyms makes answering the question at the end confusing. Other than that, it's a good lecture.

It could be improved with more bacteria (ex: for Neisseria there's only Meningitidis and not Gonorrheae, that's is treating in the Sexual Transmitted Infections just as a clinical approach)

This videos are amazing, the professor is excellent and his explications are clear

I like that professor tells very interesting and useful information. Helps to review.

He is a very Good Teacher as he teaches as if he was narrating a story.

Really nice lecture, clear and easy to understand, with a lot of examples.

Well-designed and informative I would recommend that the quiz questions can be more effective. For example, some answers are just memorizing names or some details that are only noted orally for few seconds.

Thanks Mr Kevin for your time, dedication and preparation, blessings my man!!! happy 2020

Awesome analogy great lecture! Very nice lectures overall I really enjoyed them. even though I have taught this topics and I know them fairly well. I enjoy little gems of information I received through these lectures, and new understanding

need another resource for this topic as these lectures have confused me more

if the professor says she gets it confused when lecturing she should not be teaching it.

The Professor is excellent, every one can understand easily de concepts

Mr. Pickering is a highly professional lecturer. He explains complex definitions quite simply and understandably. It is a great pleasure for me to receive this knowledge from Mr. Pickering

Amazing explanation made me understand the concept clearly in a short time

This is one of the few videos in this video series where the video cuts before the lecturer is done talking or before she's done with the material for the section. For example, in this one she only discusses E site and video cuts... what about the other 2 sites on the ribosome?

The video lectures helped me organize the information I already knew and filled the gaps in between. I appreciated how Dr. Wilson was concise and straight to the point with his lectures.

I chose this because I am a fan of viruses and I want to invent a Medicine for all viruses and I loved it very much because I want to help mankind and learn, and this is a type that we must all talk about.

It was so enjoy to understand the biochemistry and the teacher was so great.

The instructor reading off the podium is not appreciated. It doesn't entice the viewer to keep watching.

I like a lot both the explanations and illustrations to the topic.

Excellent teacher . Great lectures . He knows how to teach the subject matter

I like how Dr. Cornwall recaps chemistry and relation to energy to cells. Her hand motions help with my learning and understanding. Thank you.

two stars just for the effort. But its ore like reading fro book. Nothing different. Very boring. No interaction.

I like aging I’m pre-med student but I like a lot and now I will continue watching all usmle step 2

Great professor. Has almost everything needed for my course in Biochemistry.

Didn't explain clearly and concisely which each type of RNA was as well as providing its clear function. Additionally, it is best to provide the correct definition thus, followed by an analogy. Starting with an analogy of how the different RNA types can make the lesson hard to follow as well as, causing confusion in the actual definition of the term. This particular video was hard to gather information from.

4/5 also add on the replication bubble but as far as the other information well done i understood the concept

One of the better lectures for this complicated subject. Images and slides are well illustrated.

I like the practical comparisons used for better understanding and remembering the topic, makes it much easier and more entertaining!

Concise and to the point for basic understandment of the subject.

before I read the book but didn't get the concept. This lecture gave me the understanding of this high yield topic.

I was struggling with this subject in school and he explains it so thoroughly.

Talks clearly and explains all the key points so that you can understand the lecture in simple terms

The lecturer is very thorough and makes the series interesting

Really great videos. Extremely helpful, though on our curriculum we are required to know basic lab diagnosis of the common bacteria and identify their culture in lab practical exams it would have been helpful if that area had a section as well.

Professor Wilson gives very good examples to explain each topic of the course. And he doesn't talk too fast, that is great because I can understand him very well.

The vedios don't cover many important aspects such as cultures , serology etc. Every topic is over summarised and isn't very good for concept building

Just on the point, Lecturio is what they say it is. Thank you Lecturio!!!

The topics were categorized and explained well with good examples

I really like the way the professor make things simple to understand with real-life example, thank you , I finally understood this disease !

Good for concise explanation! I hope further deep content ! Overall content with it

Studying Biochemistry lectures helps me to understand and hold in memory every each case,,, so this is the best ever

The issues are almost complete and notes are abvious and are basic and pretty fluent lectures

Ms Cornwall Thank you for your aging lessons l have never seen such a effective and integrated videoid

Thank you dear Ms Cornwall l easily grabbed basic elements and mechanism of cell biology with your videos Best wishes

Muy buen docente, se nota que le apasiona su profesion y la ejerce con entusiasmo.

Carlo Raj,'s way of presentation is little bit weird to me

I love it... 100% worth it... Made it simple and easy to understand!

It was a great lesson thanks for everyting short and briefly everyting.

A huge thank you to Prof Ahern! You explanations are very easy to understand and your lectures are a huge help to get a better understanding of biochemistry topics. Thank you very much!

Really clear explanation with real life example, thank you so much. I had trouble to learn the cycle of this parasite but thank to this professor I get it now and only after one lecture. Even for the prevalence in the world, it's easy for me to remember it now thanks to this lecture.

Clear explanation, most of the time very detailed and easy to understand

I like Dr. Ahern's lectures, I think he is the best in this program. He's very straight forward, precise, concise and connects different points related to what he's talking. After seen these videos I went ahead and did a q-bank of a different program and nailed the ones related to this thanks to his lecture. Some people need to keep in mind that these lectures are not going to cover every single detail, but unlike lectures from others study courses, they do cover more than the basics. For broader information with specific details you definitely need to read textbooks (e.g. Guyton, Robbins, Harrison's) and " google" it up.

Great, but just too many details. Are they all necessary for step 1? I think the subject could be more clinically oriented.

appreciate very the mechanism described in this lecture. Very informative and easy to understand

It’s not a bad lecture but it’s bulky stuff that isn’t simplified to hold ones attention, don’t get me wrong, it has its highlights but it could be more interesting.

Really good discussion. I would love Dr. Ahern to by my mentor

sir , the way you talk about microbes ,inspire me to learn more.

I really liked the videos they very clear and easy to understand , they best part is they are short and precise to the point .

It's explained in a very understandable way and slow for non native speackers

Really clear explanation, and really easy to understand! I’m lovin’ it

Teaches very well. Very informative and easy to understand Lectures.

The marcomolecules lectures are very good with excellent explainations of content

I like Lecturio very much because the videos are simple, short, and hit the high notes. I got a A (first and only one to score a A) on my first exam in microbiology where the majority of the students got 60% and under.

The DNA Repair lecture was not very clear at all.

I really love how he mainly focuses on the important details needed.its amazing I love you guys.

Great lectures, very clear and understandable! Thank you, Dr Georgiana Cornwall!

Great lecture, Dr Georgina explains clearly what we are required to know

Helped me understand better some concepts as she explained clearly

It is a great parsimonious source for understanding the mechanism in which amino acids build into protein and how amino acids are broken down through metabolism into various molecules inside the body. The lecture also provides the structural frame understand the basics of amino acid regulation through metabolism.

The lectures are concise, straight to the point, and yes, fun. The quizzes also make it easier to focus, as well as help memorise important material. As with other lectures, it would be nice if USMLE style questions were embedded in the lectures for better integration of the topics covered.

The explanation is cristal clear with examples and illustrations. Good picture of ARN structure.

Great lecture which allowed me to understand the topic much better than I was taught

All the explanation are precise to the point...and covers all the important concepts

Explains concept very well with good analogies that further enhances my understanding.

The knowledge is systematic, but I wait for long time to get a answer to my questions. And I still get no feedback.

Dr. Ahern creates a great foundation by breaking down concepts and building on them throughout the lectures.

This lecture really helped me a lot, it’s so well explained and dynamic that makes it easier to understand. Thank you doctor.

Dr Cornwall has the gift for teaching!! She explains things very well, thank you!

Not too many details. Right to the point and easy to understand!

The professor is excellent. I like how he explains things. Some of the professors move their arms around a lot which can be distracting or spend the whole time looking down at the computer. With others it feels like all the do is read from the slides. However the biochem lectures are very well done and by far my favourites so far.

The lecturer touched on all of the most important points with clarity and conciseness.

He is energetic and I like that very much about him.

It would be nice to have an extra chapter o add a lab identification for bacterias. Like techniques to identify them. Oxidase positive o catalase negative like so. Also is very useful in enterobactereceaa microorganisms to add the biochemistry scale o battery examples like TSI LIA MIO Citrate Urea. I’m from Chile and i am in formation to become a laboratory Medical technologist

The module is complete but the questions can get too easy

I really enjoyed the video and it made me learn, also I liked that are short videos

I found this lecture illuminating. I think adding an image might help to clarify the solubility issue: AH can diffuse through lipid bilayer, but is less soluble in water, so would become "trapped" in urine, and the inverse for bases: B form being soluble in lipids, but not in water. Thank you for the great lecture!

absolutely wasting of time for whom needs to study for step 1

Very clear and thorough, liked it a lot thank you Dr Cornwall!

sorry about the bad rating but honestly it is not helpful for step 1 exam and the first aid book especially Dr.Vincent Racaniello, with all respect he has a lot of effort to let the student understand but not for step 1 exam, it is waste of time. hopefully you guys will fix this issue

Great Lecturer! Concise and exactly what I need! Video animation would be great to have. Thank you!

They are so awesomely explained and very helpful thank you. I’d love the videos to have that ten second rewind or fast forward arrows like YouTube does, and then it would be perfect.

Excellent ! All the lectures of Dr. Sean Elliot are amazing ! A+++

she was understandable! i liked her! i am so prepared for the next test we will be doing

I love the lectures so much. I like trip on steroids I never have consumed lol. However. I think it would be great if they had the ten second mark or arrow so that it would rewind or fast forward the lecture. It’d Save time just like you tube videos and stuff. Thank you kindly

Very concise. Great illustrations. Thank you. Thank you. Thank you

It was a Great lecture :) felt it very well organized and presented

The topics get into my mind in the first go

The professor did not do a good job explaining concepts clearly, went too fast, covered little material

there wasn't enough details at some points. The topics, for me, are a little tough and the techer wasn't seems to be confident with the material. although the slides are very helpful to understand the topic.

Concise, easy to follow, great drawings, post questions provide a good summary of key points before

Thank you for your knowledge and for spreading it in this way for us, the students.

HE has the lecturer super powers, funny sometimes too, makes you want to know more.

Great but insufficient. The second part has no subtitles for foreign speakers

I couldn't follow this lecture - it was not presented well at all.

Surprisingly interesting and short course. Ms. Cornwall is fun to learn from.

amazing lecture, finally i understood the tertiary structure for the first time

The lecturer makes the topic interesting, easy to understand. One begins to appreciate how these things link with everyday human existence and how they play a pivotal role.

Good and informative, no bad comments. Good lectures and lecturer

Good, where are the rest of the organelles (like peroxisome)

Need lot of detailed explanations.. especially in videos. The teacher is really good but the script is lacking too much.

Short and interesting course. Binged it in one sitting. Ms. Cornwall is a pleasant lecturer.

I choose this rating because the lecture was so clear and and simple that made me rethink about the initials steps in the study of medicine.

A calm and organized lecture made in a way that is easy to recollect with the start and end saying what we are going to learn and what we have learned.

A most clear, fun lecture on the respiratory burst so far!

Excellent ! I finally understand the topic after forgetting it many times ! Much better than First Aid !

its good and thorough, also covers minor lipid types! good to learn

Faltan aspectos microbiologicos como factores de virulencia y patogenia, pruebas de laboratorio, y enfermedades que produce.

Simply explained with a little history that made it fun and also helps keep the connection to the content, So much of medical knowledge is facts and figures which can easily become blurred in my mind. The connection to history helps this content stand out in my head! Thank you!

The professor's way of teaching precisely saying his clear and neat approach to the lectures is what makes them great.

I love her lectures ! Relevant for the USMLE and fun ! Recommended !

Concise, easy to understand and relevant for the USMLE Step 1. Very good ! A+++

Concise and relevant for the USMLE Step 1! Easy to understand !

Explains it completely from the start to the end , everything is clear and simple . The structure is very easy to understand.

Dr. Shukle, I really struggled in applying the information from this lecture to the quiz. You have been great otherwise!

Thank you, this is helping me so much. I love these videos.

It helps me a lot with my presentation, I was having a hard time understanding this topic and after see this lecture it becomes easy to explain. Thank you so much.

Dr Ward explained every details in embryo development so clearly, I love his lectures.

I really like the lessons and I think they are really useful

Dr. Ahern, I appreciate the pharmacological and pathophysiologic connections you make when delivering your lectures. It aids retention and usefulness. I am a nurse practitioner student and can also see the clinical connection. I have administered Methotrexate to many patients. Thank you.

Wonderful examples of the Hardy Weinberg principle. The exercise is explained step by step and is understandable in the first explanation.

I love this app but can get a little confusing when the professor uses the wrong words or accidentally says the wrong thing. Do you not edit errors out? It’s a great platform just needs a few tweaks here and there.

The Pro. ist amazing and has a very clear way to introduce concepts The informations lack any medical relevance, they are directed more towards biological knowledge Please, try to be more oriented towards medicine, Sings and symptoms are needed

Very high-yield. Thank you for underlining this moment, crucial in treating hypercholesterolemia.

Not a great virus review course for Usmle step one students

Easy to understand and fun! Really useful! Great examples are provided!

Easy for a non medical professional to understand and digest the material

I have taken biochem as an undergrad, grad. and post grad and I've never had anyone explain things as clearly. Dr. Ahern is one of the best teachers I've ever encountered. Thank you!

La sintesis de los temas a desarrollar estan muy bien elaboradoos , seria mas comprensible si las traducciones se pudiesen leer con mas facilidad

Excellently Explained about the transport and clarifies doubts regarding the different transport modes in membranes

Amazing course. It really makes you understand acid-base balance.

I am a student at Downey High and I really want to be a cardiothoracic surgeon, and I didn't know what to learn but I know this website will help me.

Gives you the basis and covers the necessary topics for a good understanding .

I was able to learn a lot in a short time . I particularly liked how she simplified the material

Thanks, Dr Georgina, for your excellent explanation during all this lecture.

wonderful details & very enjoyable teaching way - u really know how to teach pathology thank u

well most know that shigella destroys gis mucosa...but the pathophysiology is now clear...thanx lecturio

It is very audible, good sound system, analysed with pictures and really more defined

This is pretty good introduction! haha how to control the cell cycle

perfect and it was easy to follow . i like the way of questions

just basic to litle details course.easy to understand it.

I thought that this was very thorough and went over lots of the material that my current professor is going over. Some of the questions were either a little simple but reiterated take home points, or were left-field as the material was not covered in the specific video I just watched. Overall I would recommend this course to anyone struggling in genetics + read the comments because she does a great job in answering and clarifying questions you may not know that you had.

A+ teaching style and delivery thank you Dr Ahern for making a difficult topic easier to digest

I think it is an entertaining way to learn the history of Biochemistry.

This set of lectures on Staph were very generalized and did not cover the other Staph bacteria commonly seen on STEP 1 (i.e. saprophyticus and epidermidis). This seems to be a common theme of not going deep enough to cover material necessary for STEP, yet advertising that you all cover enough material for STEP 1.

Excellent lecture. Clear explanation moves step by step with many examples.

This particular class video is not very helpful at all. I feel like genomic imprinting can be explained more efficiently and more clearly than what is portrayed in the video.

Actually I saw the YouTube add . And I watched the lecture . The information is given in short and precise manner. Understood everything.

The video helped me understanding this topic with visual representation

Really solid course taking you through the basics of acid base balance and disturbances as well as a great method for figuring out clinical cases with ease. Bravo Dr Wilson for this fantastic set of lectures

The material taught seemed to comprise of only 10% of what we need to know for USMLE. Various bacteria ranging from gram positive cocci all the way to mycobacteria were all missing. And even with the bacteria taught ( streptococci, staphyloccci , vibrio , e.coli , shigella, salmonella) lacked a tremendous amount of depth. Very disappointing that I paid for this. Hoping virology lectures will be better.

I love this guy. The way he explains makes Biochem look easier

I really liked that it gives you the information you need and the way the lecturer explains is very clear and easy way.

A very well presented and in depth explanation of biochemistry. Dr Kevin Ahern also responds very quickly to questions. Definitely would recommend to anyone struggling with biochemistry like I was !

too fast too fast too fast too fast too fast

''The best''.it is my first time studying physiology and really enjoyed it...I think all the concepts are into my head now through the lecture..thanks much..

I loved the correlation with margarine and butter, it helps to understand and remember the topic.

He is clear, short, and simplify the most important points

it is really amazing lecture & has been organized well thank you

Nicely explained. The Prof. Has exceptional abilities to explain complex concepts

very good and excellent lecture.i like it.very good presentation

I loved how I understood the bigger picture in the end of the lecture

I appreciate that the changes were made according to reviews previously posted by students. It helps that the information is staying up-to-date for all users

Clear and Comprehensive explanation. Not too detailed but enough to understand.

he is very clear and is a nice teacher, and he use a appropiated nivel of technicims

Clean and clear. Simple explanations. He knows the subject for sure.

Quality is "where you find it". The lecturer goes over a lot of information with a very pleasant demeanor.

At first, it was quite hard to listen to his lecture but later, with the help of subtitle, I found he taught in an awesome way which helped me to understand it. He might talk fast but he is a good teacher

I like so much the content of this course and how the doctor provide the information

nothing could be better, I liked your way and simplicity with fully clear explanations.

This video, with the previous two videos are amazing. Taking embryology in med school was like greek or hebrew. Your teaching style is very helpful to dissect the processes into understandable segments. Our professor taught by day of development so there was lots of jumping around. I like the discussion of one layer from flat layer to cells to folding, to closure, etc. Very well done. Moose Henderson, PhD

Very first time that I have understood completely acid base balance/ pathology. Beautifully explained!

clear helpful illustrations. although history took much time, but I liked the way you went through it, your slides also were simple, not crowded and well organized.

it's very clear course with direct points and simple explanations.Also the notes and slides are well done.

It tells the information is not really close to the USMLE questions.

Simple and easy to understand, he really likes the subject. I wish the videos were longer with more information. Maybe an advance lecture? Thank you!

I found this lecture very concise and easy to despite being quite basic. I have always struggled with understanding atomic structure and feel that it's due to information overload. This lecture provides just the right amount of information to build on.

there is a confusion between cds and sylial on neutrophiles, overall it was good

I really liked this site ,and it's seems helpful for me . I am a high school student. I am in the 10th grade right now. I just want to become a surgeon doctor because I want to save peoples lives. I know that I have to right a commit to this site and I do not have to introduce myself for you people. I do not need to study this because I did not understand today's subject.I just want to be ready for the medical school. I hope this website will help me being ready and ,Good Luck.

Mr Racaniello explained viral genetics very well in this course, however clinical diseases (measles, mumps, hepatitis viruses, etc) were not mentioned. Most importantly, HIV was not discussed.

I finally understood why we have Lineweaver Burk Plot and how we read it.

Mr Racaniello presents all of the material very well and I believe that he is an excellent lecturer. However, there are many important types of bacteria missing from this course. Pseudomonas, Treponema Pallidum, zoonoses, Clostridium, Tetanus, Helicobacter Pylori, Neisseria, Bordetella, etc. USMLEs step 1 go into great detail regarding many of these bacteria that were omitted from this course.

i knew next to nothing about molecular genetics, however after 6 weeks using lecturio ive gone from 20% in the practice tests at university to 70-80% each topic is subcategorised, easy to follow, and Dr. cornwall not only illustrates brilliantly but also delivers the otherwise difficult to understand material in a clear and concise manner,

Concise with good use of slides and professional presence and dress.

I thought it was just like my professor very concise, with powerful imagery.

P53 GeneRate this lecture P53 Gene Rate this lecture P53 Gene P53 Gene P53 GeneRate this lecture

Very useful for people who don't know much! Concise, and well explained!

Very in-depth discussion of X-linked inheritance. A very good resource for studying for exams on human genetics.

The mechanism just summarises all the information into one picture

So many sub topics are missing. Please add new lectures to cover those topics. Bacteriology portion is incomplete

Was very clear just speak very quickly, then I have to repeat the lesson to understand complete anyway its not important, I would like just when speaking about the oncogenes give some examples about the food that causes

I liked it very much because it helped me access materiel that I already new without further complications. It was very easy to comprehend and I will recommend this to everybody needing this for whatever the reasons you need it for.

Appreciate too much, because after many readings in the books, finally I understand clear having the big picture of this topics . Congratulations to the Teacher .

He's pretty funny and has a clear lecture style. Very clearly laid out

Well taught and succinct. I enjoyed his style of lecturing, as he uses good intonations.

Very much explaining After I did this topics know is easy to undeerstanding

she looked like she was reading from a script and not focused or natural.

extremely helpful when the amino acids are divided in functional relevance.

Great lecture. You have a great and enthusiastic way of explaining.

Perfect way of explaining complex things. This is rarely seen by lecturers. Wow!

yes, very good! Very rethorical and good lecture. I love lecturio

Amazing lectures. Simplifies complex pathways and process. Really fantastic! Watched every lessons.

Her approach (straight forward) to each process. Question: please detail the lewy body difference in dementia vs the lewy bodys in Parkinsonism.

she explains it to the point and doesnt waste time going around the topic.

In the lecture Thad says that ATPase is a V-type pump, but in the test it is a P-Type pump, which is correct. This pump is called a P-type ion pump because the ATP interactions phosphorylates the transport protein and causes a change in its conformation. There should be a review process to ensure accuracy before these lessons are released. Overall a great lecture, but details like this are important ones not to miss. Thanks!

Nice one, well described, nice talker, I enjoyed a lot. Keep it up!

This lecture was explained super clear and to the point. Thank you!

Well done! Very targeted information. For those that say it’s not as deep as their classroom lecture, it is not designed to be. Again,what we are supposed to get out of this course is the high yield information...and we are getting it. Thank you so much Dr. Cornwall.

Me encanta, todo bien conciso, de manera muy explicada y digerible de combrender

Clearly explanations, every piece of knowledge that prof. Ahem shares with listeners is facilely absorbed and stays in the mind.

Attaractively and well explained video of serine protease catalytic mechanism that I have ever seen...Thank you..????

:) Thank you . everything in this lecture is clear. like it very much.

Very eloquent :) my favorite on this website! would definitely recommend.

thanks for your helpful for the all lovers of education

A good introduction. Very schematic and overall easy to learn basics.

Easy to understand...high yield information....great graphics,well done!

he is too fast and diagrams used in this lectures are different and we cant imagine and is tough to understand. i saw the YouTube several times to understand what he is saying

very confusing explaination. he didnt exaplin the concept properly such that we can grasp it. pls try to explain the concept properly

Easier to comprehend with the use of great illustrations. concise and crisp presentations

Too fast I can not understand and imagine. Youtube animations are better.

not detailed and for a introductory vedio should be more explanatory

Never Understood this concept so easily until Dr. Wilson explained it on this forum.

Made it very easy to understand. Thank you very much!

This series of lectures saved me days of studying in my exam period in 1st semester of medschool :)

Almost no information really disappointing. Use Step 1 2018 page 46 ... Even a student could have presented the topic in more depth as it is important.

really liked the explanation of disease followed by management, very practical way to learn

very nice and efficient lectures, you have to write some notes to your book from this lectures!

a tough subject, but Dr. Georgina made it very easy and palatable, thanks soo much.

I just want to admit that this tuition is a hard one and she made it very easy.

just excellent , the content and the preparations were realyy excellent and goes very easy.

I believe that she is a great lecturer but, the issue is the way of delivering the lesson and how much was she ready to record the tuition. anyway it was a good experience for both of us, she let me search a lot for the genetics to unwind condense informations :)

This is only the first lecture and the first time I am delving into biochemistry for the first time, so hard to say, but something about Prof. Ahern's manner makes me curious and creates a fine feeling of anticipation. Great for a first lecture.

Very disorganised way of explaining concepts It would be much better if things were presented in more detail and if the presentations were structured adequately

As a Danish medical student, with English only as my second language, I admit, I had to spend some time "tuning in" on Dr. Raj's way of speaking. See, he's an extremely fast speaker, but as I did get used to this, I really learned to appreciate his way of teaching. Actually, his way of speaking kind of peaks my attention and focus, since my brain has to work harder for it. Thanks, Dr.!

Concise and clear beginning in cell biology and homeostasis to warm up.

Never understood this much better than today! Thanks a lot for for doing this.

I was already following him before knowing lecturio. Nobody explains Biochemistry like him! Thumbs up!

it was described in a simple and easy way to understand, thank you.

I think that this course is a incredible tool for medical students. I belive that it's important the Microbiology for doctors and it's great that we have access at it's information

Claro y directo, ayuda a entender muy bien los principio básicos de la fisiología

This video did not really show Aspartic Acid or Glutamic Acid?

The lecturer did not appear confident looking into notes too often. Too many hand gestures are a distraction especially when not pointing to the stuff on the slides. The material was not presented in an easy or simple way. Made it more complicated that it actually is. I feel difficulty in continuing to the next lectures without understanding this.

Lecturio is Awesome! I am not a student but all the material I have been through so far is of HIGH quality! My best investment ever!

He very easily simplifies things. So this is why I give him a five star review

Great set of tutorials. Ideal for a quick recap before an exam.. Thanks a lot.

w/ very clear explanations! i also like how the points are very clinically relevant. thank you!

Amazing, loved it very much. Easy to follow and clear.

The course is concise, to the point, good source for a fast review. But more details do not hurt too

amazing ! thank you so much dear dr.Ahern , i was always scared of biochemistry ,but its the first time i finally get to understand it and i owe it all to you. My committee exam will be in two weeks and im hoping to finish this course plus few more lectures from fat metabolism course. also special thanks to lecturio for preparing such a great learning system opportunity for us.

Excellent. I had no problem answering the folkow up questions. I've read about most of these concepts during a biochemistry course I followed earlier, which probably made it easier for me to understand interpretation of the curves in this video. Gives a good overview, so thanks! Sincerely, A Danish medical student

I would love to give a higher rating but many important pathogens are not covered

Some points are not stated clearly enough. Overall, good presentation.

concise and straight to the point,exactly what I was looking for

I wish all professors prepared students for Biology courses with this explanation. Thank you for addressing this concept!

To the point, clear, precise, great tone and flow. Well planned curriculum.

Amazing lectures! Very well explained and effective videos. A perfect way to get a clear view of the subjects, very glad I found this.

So, during my first two years, I thought this course was a little on the light side, and it feels a bit as if the instructor is more stating facts rather than explaining and linking ideas. I know they tend to keep the videos short, but I think this course could have benefitted from more time, from a learning the material stand point. As a video series for learning, you might be left wanting with just over an hour per subject. As a learning source, 3 out of 5. So, now on to why you should really give this guy a watch. I was looking for a quick microbiology review during my dedicated study. I had watched sketchy, and read the textbooks, but wanted a quick, solid review series to watch during lunch and dinner during my dedicated, something a little bit more to the point than sketchy. This lecture series is the holy grail of high yield review that is exactly what any student looking for a great microbiology source to watch during their dedicated study. It is short, to the point, and highlights what you need to get most of those micro questions right on UWORLD and has the images in the slides that you need to be able to recognize. High yield review source, 5 out of 5. So, overall, I would give this series a 4 out of 5. If your a first or second year, this might not be the best choice for microbiology, however as a high yield review I would rank these microbiology videos second to none.

Awesome lecture, awesome proffesor. My teacher spent almost 1 hour explaining that. Thank you Dr. Ahern

Nice succinct intro with basic overview -- key points are highlighted

I feel like she is just reading notes that she has been just handed over.

5/5 because of the simplified explanation of the human microbiome. I like the approach used because it sets the stage for acquiring important high yield information later into the subject.

Dr. Wilson's delivery.....WOW....Really appreciate this and pray to God to be able to retain same for massive exams on Monday

The presentation is simple, short and concise preparing students for more detailed content. I believe that this is an efficient approach toward a broader base of an audience. Thank you!

as a beginer i didnt couldn't understand anything the lecturer is talking about and the lecturer is way too fast

For the first time ever, I got AA right. Thank you!

I'll just say thank you very very very very much!!!

My name is Barbara, I'm from Colombia and I really like your videos Mr. Kevin, because I think the content is easy to understand.

informative course, to the point, easy to follow and understand, quiz questions are interesting

You do a wonderful job of clearly and concisely breaking down concepts.

the course was good, the first video was condensed with a ton of information and I think you should maybe think about splitting this kind of videos in the future, I was finding myself watching other youtube videos to study this subject. it is always good to use plenty of different source of information to develop a wide perspective on a subject. but in this case, I want to rely on lecturio only.

Vitamin section is fine, concerned vitamins explained clearly and easily However, some water soluble vitamins are considered missing (eg. thiamine, riboflavin, biotin, vitamin C ) although they might be encountered in some other subjects; such as nutrition. Additionally, minerals are not touched in these lecture series at all Overall, it is a very good course for the material targeted, but needs to fill the gap of missing items

Pure gold indeed !!! Presentation of chemical compounds during presentations is very helpful.

Good Lecture, the curves were well explained. Wish they talked about Chirality a little bit:)

I really love these course! Great work breaking it down and offering the quiz it really helps!

Dr. Cornwall is very thorough and paces herself very well in relating core concepts.

Highly organized and well structured lecture. He clearly sets out events on a timeline and explains what happens. Engaging.

Really great lecturer who utilizes excellent diagrams. Engaging and easy to follow.

Love him so far, clear concise and to the point and also very enlightening

very clear and visual, good speed, nice images and accessible vocabulary

most of the things i catch from animation while only little from lecture (for which i had to pause the video to read all those stuff written there, which is time consuming). mam's speech seems quite a kind of nervous, suffocating type

Muy buenos videos, tiene mucho conocimiento y lo explica de una manera sencilla que podamos comprenderlo de forma clara

As a lecturer myself in another field you make something that is difficult easy to understand for learning transfer = A+ delivery thank you

Beautiful calm lecture style delivery and explains concepts simply - thank you

it is a very interesting materail, so clear an usefull and could recomend it without any question

Great lecturer. Keeps the lecture interesting and easy to remember. Wish I had him as my professor.

Yea, these lessons site wide need more quiz questions. Only thing holding this site back from being outstanding.

I liked his explanation: first the context and then see the Alzheimer's itself.

Very well explained and detailed lecture, but it would be nice for better understanding to have some names and terms (e.g. Ramachandran plot) displayed in the video!

I liked the course. informative, easy to follow, to understand and to memorize, However, I have noticed that many topics/ microbes have not been addressed (TB, N.Gonorrhea, T. Pallidum, Leprosy, Mycoplasma, clostridium ....... ). Although those might be touched in other topics such infectious diseases, but they should be highlighted in a microbiology course. Would recommend the entire Lecturio to my daughter who just started her first year of medical school. Microbiology is supposed to be studied during her 2nd year though

way too fast ????I really wish the teacher would talk slower as now I keep having to pause and rewind etc.

Great course! Check the MCAT: Microbiology Course for the pre-cursors of these USMLE Step 1 lectures (overview of gram staining, cell wall structure, etc).

Genetics generally is a very confusing part, I think she made it quite interesting and I grabbed a whole lot

The explanation of concepts were precise and focused. I like the pictoral representations I'll recommend the lecture to my friends, who are taking USMLE Step 1

With all the rrespect the spoken language is blurred, I can’t understand properly, plus your eyes are focus on something maybe an aid material, it would be better if instead they were focused on the camera and try to explain rather than read. Thank you for caring.

5 rating is what you deserve , i really liked the way you illustrate those key aspects

Me parecen aportes concisos y oportunos. El Dr. tiene un compromiso con los estudiantes tal, que traspasa totalmente la pantalla. Me ha encantado. ¡Muchas gracias Dr. Raj!

So much more simple than my lectures. Thanks for the detailed lecture. You're a life saver.

Direct , and easy to follow. The length of the video also helps.

that was a simple and accurate description i liked it very much

I needed an update on genetic like this one, i like the way is shown every part and all the details within, i recomend this article to everybody.

"... and we know that the DNA was taken up because the plant grows tumors OR NOT..." Taking the term "tentative scientific language" to another level!! LMFAO >D

Great professor but unfortunately the details of this lecture are not important for USMLE Step 1

This course was informative and professional. I look forward to learning more!

Very calming, understandable, and professor knows what information is right to share

Easy to understand and the explanation are very clear. Thank you very much good job!

In my school we will take this lecture in 2 hours!!! Way too short and superficial

well done, explained thoroughly, yet concise. Having a minimum word count on a review is a deterrent; please change this.

He makes it very easy to understand. I learned so much from this video without even realizing it.

lectures are very exciting and informative provided someone have basic knowledge of genetics. With reference to USMLE, I am afraid to say that is it is helping.

THANK YOU Pro Ahern you're amazing! very well explained!

Professor Ahern is a perfect teacher and he makes everything so easy to understand

A brief but v helpful quiz in re-freshing the concepts...it helps in our routine practices as well...

Very interesting topic can help in personal life as well

He tenido problemas con la clase de fisiología, porque no puedo comprender del todo lo que mi profesor está diciendo, por ahí escuché de Lecturio, y estoy muy feliz, porque pude entender muy bien lo que estaba enseñando.

Needs more details, and take it slower so that we the audience can get a more thorough understanding of the topic (the video really doesnt need to be that short)

Dr. Wilson, you are my hero, you made this concept of acid base balance so easy for the first time in my life. Thank you so much!!

She talks too fast. Also reads too much from her papers. Seems like she's not sure of what she is teaching.

She talks too fast. Additionally, she reads from her notes too much, strikes me as someone who does not have a firm grasp on what she is teaching.

I found it really helpful. Your explanations were clear and easy to understand.

As much as your stories are interesting for the ETC gradient It does not fit my learning style. It would be nice to have clear scientific language about what's happening. I can't write a story on my exam paper. Perhaps this is just me.

concise and dramatic. Simple presentation well presented. A little spice in illustrations.

Highly recommended lecturer for Biochemistry! I like his method, he is attractive teacher.

Easy to understand and very complete. Thank you for your time, helped me a lot

Brilliant lectures, really helped to consolidate my learning. The associated test questions are a pain in the ass though, please supply a reference range with the question... we use different ranges (units) over this side of the pond :0)

Thank you for the video's theses are really helpful. look forward to keep learning.

Feels like she is not comfortable with information she is teaching. Accuracy of information (and spelling!) is sometimes questionable.

Assalam-o-Alikum! Sir your lectures are very informative and its my humble request kindly give us access to download these lectures because lots of time taken by lecture due to internet problem plz try to understand and give us access of downloading

I love the clinical application. It makes it so much more exciting to learn and remember because as Dr Carlos Raj points out it's not just memorising. I must say his way of speaking makes it even more exciting :) On a serious note though-mentioning how serious it is to act on dysplasia or when the BM is involved-we should be saying omg, and not looking at him. Looking forward to more lectures-wish he was lecturing the subjects to keep that interest and significance of the subject and our job.

very nice clear and organized lecture. thank you. it adds alot to my simple knowledge

The lectures are concise, very to the point but yet hit all the critical points and it is very easy to understand. Embryology for me is really difficult to picture. However, after watching these videos, I feel as though I can finally make sense out of what I am reading and what is being presented in class.

Great Explanation !! I wish we would have had you as a teacher. :)

thanks for teaching me in such a clear, precise, and yet enriching way

Clear and concise. Also appreciate the pace that he was going. Wish there were more questions though

Wow! Muchas gracias por todo el contenido muy bien explicado! Realmente fue muy interesante y, de gran aprendizaje asistir a todos los videos del curso "Introduction to Cell Biology".

Clear explanations provided with diagrams that helped me follow the explanations

Thanks for focusing on the "big picture!" The lecturer at my school bogged us down with the details, so it was hard to take in what the most important steps were

I Have watched only the free videos of basics of biochemistry as I seek to do Step 1 as an IMG. I like the smooth transitions and the questions at the end of each lecture. I seek to subscribe for the annual package soon.

Wonderful presentation of complex hard to understand topics. The teachings were made ridiculously simple.

It explains the most important aspects of acid-base disorders and gives good examples for us to understand the concepts. I personally liked his explanations very much.

excellent lecture. Cristal clear; not too slow not too fast, smooth transitions and a bright ending

la clase fue demasiado concreta, tuve que pausar para calificar al profesor

Great attitude and non-verbal languages. You make those vitamins more easier to understand. I appreciate it. Thank you and keep going.

Its hard to pay attention on her lectures because she always pauses to read her notes.

A very good lecturer of Microbiology. Thank you and I am looking forward in learning more.

prof Ahern is wonderful and funny! enjoyed all his lectures

It was very precise and up to the point. The presentation was interesting that triggers to study better .

I don't like Carlo's style of presentation. It is also at odds with Robbins and Cotran. The worst video on Lecturio

i feel that u r teaching better than other professors we as a student understanding better micro as step by step

very good lecture. pretty well organized and instructive. He has a deep knowledge of the material making me to pay special attention to all his lectures.

Very nice and informative lecture, easy to understand and remember

I have followed Dr Ahern through all the basics of biochem lectures and he has never failed to deliver.

Great job again Dr. Ahern! You have helped me better my understanding of these topics.

Great job, Dr. Ahern. Thank you for bettering my understanding of these concepts! Used as a supplement to lectures and powerpoints, your videos on Lecturio have been extremely helpful to me!

Excellent overview of Aging topics. The video lectures were quick to the point but were also able to give just enough background information on each of the varying material.

great lecture, very simple and clear. I've finally understood bonds!)) thank you!

Very good lecture, l consider that is one of the most complete themes that l´ve read ...good job.

very informative and well explained lecture. Dr. Kevin Ahern has changed my view of biochemistry.

Brief, understandable, high yield information explained with illustrative slides by Dr. Ahern

Very well put. Dr Kevin Ahern explains difficult topics in a very short concise and interesting manner.

I am a biochemistry student studying in the UK I found this so useful especially as a foundation in my initial year of study.

I love the visuals, her method of speaking and the transcript at the end

This material was delivered brilliantly by the course lecturer. I have really enjoyed the nutrition lectures by Dr Cornwell and look forward to future lectures by this lady.

Amazing lecture! Loved listening to this. Great explanation and makes it interesting to watch.

I liked how strep was broken down between group A and group B but the video didn't mention the different types of strep in each group ie s. pyogenes. The quiz asked about catalases but didn't mention it in the video.

things made quite easy with interactive lectures and slides and tables

I will going to enter to the world of pathology next semester and i really didn't think i would like it but this videos might have changed my mind, Thanks Carlo for this material

The combo of visual and review aided in maintaining info

This lecture and the one before were very confusing. You need to explain that the third energy level can technically hold UP TO 18 electrons (s,p,d sublevels) but it also fills up with the first 8 it receives. valence shells (energy shells) and energy LEVELS need to be better distinguished and not used interchangeably. Luckily, I knew the material and was able to straighten things out for myself using Google. How can I know that Lecturio will not have faulty lectures in the biochem module (material I'm not familiar with)? I am still within 10 days and am considering cancelling my lecturio subscription over this lost credibility in my mind.

It is very clear to understand. Great job Dr. Cornwall.

Prof Cornwall does a great job at presenting the material, catching my attention easily into the depth of the material while being precise with the content. Very easy to learn from :)

You make it much more easier. However, I still understand all important points. Thank you!

This guy deserves a medal. I wish I had a lecturer like this when I was in undergrad (or even now in medical school).

This entire series is the most eloquent and beautiful explanation of a terrible terrible subject like biochemistry I have ever seen to attended

She talks so clear, understandable.. just a little fast but i havent got bored.. Thank you..

it was very good,and helped in understanding the basics

I love it so much!!! It’s been a truly rewarding experience for me!

Good lecture, but not USMLE focused. This is more of a general biology lecture than a USMLE prep lecture. It seems to me that Lecturio is not making the difference between MCAT prep and USMLE prep. The lectures look more like MCAT prep lectures and not USMLE.

I like the way she expresses, you can easily understand her

Very good use of examples connecting to every day life.

Very helpful. Just passed final exam of Molecular biology and Biochemistry I-II with A+ Lectures are clear, made me understand the topics well sinceI had a good concept about the basics I could absorb more details and could recall immediately when needed. Highly recommended.

I have reviewed the curricula for several physiology modules and found them excellent!

Very simple and to the point... easy to understand each and everything

By my opinion, very interesting and informative lectures. Thank you very much!

Hello Dr. Ahern. Your lectures were phenomenal, but for several of the lectures the slides did not correspond with your lecture (they were of totally different topics) or they changed midway into into unrelated biochemistry topics. It may be best to review them and adjust the errors. However, your presentation was so so good that I was easily able to follow your lectures with the downloaded lecture slides.

best prof in the world explains everything so good that even a kid will understand

Its a little bit dificult to understand but the information its complete and tables and graphics helps a lot

excellent i learnt many things from this lectures (Dementia is very important problem) thank you

VERY CLEAR AND EASY TO FOLLOW! IT CAPTURED MY ATTENTION. ALSO LIKED THE FORMAT

Really great explanations of the whole process. Was not happy that I had to relearn Krebs and ETC but actually found these videos enjoyable and valuable.

i like how he explain all and the images like support are amazing

The lecture are awesome. It is just easy to understand Thank you very much!

Great enzyme analogy! Enzyme is the friend who puts his two other friends in contact with each other so that they can start talking and dating ;)

Nothing on how p53 relates to RB or how p53 induces p21 to inhibit CDK thus acting as a tumor suppressor by not allowing cell cycle progression. This info is found in the the First Aid for the USMLE so it is probably important.

I like the smooth flow of the subjects in this course and how they focus on small details that make you digest and understand the living human from very small details.

In terms of studying for something like USMLE, brief intro is fine! Such topics will not be tested on the exam but are necessary to build foundations for other future topics. If you are studying for other exams, this whole module may be a bit light on key information. Great as a refresher though!

Conveyed the process in a short &digestable way.I LIKED THE WAY OF presentation too.

Interesting and engaging, definitely someone i can follow and learn from.

Not bad, but need to identify the polymerases better, as in the replication of DNA and RNA...

It was easy for me to follow the professor as he was explaining the materials. I could understand the concepts and the process.

Had so much difficulty learning the enzymes on the pathways. This way was easy to understand it!!

his teaching is clear and it is not allowing me to get even a single doubt

i could understand the concepts better. explanation was good.the charts were self explanatory. it made me feel bio chem much more interesting.

I'm a foreign medial MD internal medicine specialist and I came to us I just felt lost but when I find this tools my life just changed! I already suggest This to other physicians here in USA. I hope I can pass all the usmle steps I will let you know guys!

the acid base balance section was great. clear, precise and the acid base box just made it all click. Fantastic!

The lecture was clear and the material is high quality. I wish it was made a little bit clearer what the neural plate is.

There is possibly a mistake in galactosa geometric formula in the lecture

I’m following this course as I’m attending this course at my university, it very helpful, but I wish it was as detailed as our class are.

short and sweet concepts. nice tables. easy to understand. thank you.

I like the way you link things from one to another. Yuu made these lectures highly appreciated with the concise and comprehensive explanation! Thanks Prof!

really helpful i never found this data in any of my textbooks

This is a great lecturer who gives great detailed explanation. Unfortunately, he's limited by Lecturio, as it hasn't been able to incorporate videos as visual aid to the lectures yet. Embryo, particularly, is very complex an image to mind picture, especially to young learners, and when you feel there were a few things left to imagination, you know something is missing. I believe videos would be the cherry on top, and would make a great tool for what I think it is almost a perfect way of learning, as it is Lecturio and its lecturers.

This is not a USMLE 1 focused topic, an important material for the step, it's so superficial either the question that is a first order question. Need to going deep in the topics, we're not an undergraduate students.

Not my favorite subject but very well explained and understanded.

I like it because it is really going to be perfect for my learning and I liked everything from it! It was really great taught by the Educator.

I absolutely love this lecturer. He goes straight to the point, gives high-yield and applicable information (lots of information btw) in a summarized awesome way. 5 starts no doubt.

thank you very much finally, i understood embryology you made it easy, understandable, and fun to learn

She broke it down to the very basic and helped me get a good foundation

The explanation is very clear, I'm early to continue watching more videos.

Understood the lecture clearly. Very impressed by how clearly he explains things.

Wonderful! An awesome lecturer, he just has a unique way of passing the message. Great work Sir

This guy is fantastic lecturer and the best on this platform, knows the subject matter, knows how to capture your attention throughout and also has a way of going over everything in a short summary. However, I would have appreciated if he becomes more test oriented. Thank you.

This guy is the best lecturer on this platform, knows the subject matter, knows how to capture your attention and also has a way of going over everything in a short summary

He explains it very well and at a good speed. He doesn't use to many difficult words so if your first language isn't english it's still possible to understand. Also whenever you have a question he answers quickly en thouroughly.

It is really helpful. I appreciate your kind efforts. Thanks verh much.

i like your teaching .sir. it helps me to understand the concepts clearly.

Excellent information and explanation, it's helping me a lot. Congrats, lecturio!

Me encanta como se enseña! Ya quisiera tener una profesora como ella en la Universidad!

I had to try so hard to follow what lecture was teaching, subject matter is quite abstract. All the same thanks for trying.

I had to try so hard to follow what lecture was teaching, i remember i enjoyed this better in med sch. All the same thanks for trying.

this topic is quite too cumbersome and lecturer didn't seem to be in control of material presentation

Great lecturer very knowledgeable of subject matter at an admirable pace. Needed this in depth type of lecture in med sch. Good job

Nice intro to genetics, subject that's usually scary but very well carried out. thank you

great lecturer with an incredible pitch and clarity but this subject rather fees boring and i tend to get the post lecture quizzes wrong but its all good. I need to read elsewhere but all the same keep up the good work.

great lecturer with an incredible pitch and clarity but this subject rather fees boring and i tend to get the post lecture quizzes wrong but its all goo. keep up the good work

i don't know but sometimes its very difficult for me to follow lecturer and i get confused with interchangeable terminologies but great job overall.

A very difficult topic which is highly volatile to forget, but lecture does his best to keep us informed

It was just amazing, he was critic to give information and had the most important skills for me, and that is: perfect didactic. Had all concise information I needed.

Like it very much. Will like it more if you can add more bacterias and viruses on the course!!!

He simplified the concepts and illustrated by a very nice way

Great Teacher, enjoyed every single second watching these lectures. I couldn't ask for more. Great lectures Ever!

First of all I would like to say that I really appreciate all of the effort by the professors and Lecturio to do great lectures, however, I would like to say, as well, that you need to focus on the exam format (In this case - USMLE Step 1). For example, in this lecture it was asked: "Which of the following is NOT a lysosome related disorder?" that is pretty good, because it has a clinical context with the subject, however this " lysosome related disorder" have never been taught by Professor Cornwall.

Very good presentations, accurate and to the point lectures. Love to study with you!!!

The explanations and images are well coordinated, making the review more interesting

Excellent delivery of content which was easy to understand Good use of diagrams and graphs to help explain key concepts

The explanations and examples were clear and right to the point

informative. good review for this basic area as it has clinical correlations

The professor makes the subject matter interesting and understandable for the layperson.

Hello! I have not finished all the course so I can not give you a proper feedback. but so far I really liked it and it has been quite useful. Thanks.

Lectures very good. But i wish you had some themes like giardiasis, amebiasis and others.

This lecture helps me a lot since i jave a hard time to understand.

Very clear what is going on. I understand it much better.

Prof Kevin Ahern makes even a complex signaling process easy to understand and the association with day to day events. I have loved his other lectures too. I literally used to hate biochemistry but now I’m enjoying it and that is why I have given his lectures 5 stars

very good outline and examples given in a step by step manner. Getting to like biochemisrty after years of putting this subject aside. Thank you.

Loved the lectures, especially the lecture on the electron transport chain. Dr. Cornwall had a really useful analogy of the ETC and kids (electrons and hydrogens) going to the prom (ETC) that really made the concept stick. Very good job!

I find that I get used to her style, I wish that all the courses be taught by her

It is very concise and practical it helps me a lot to understand in an easy way the collagen process.

The chapter about cellular structure has given me clear explanation and enhance my knowledge about the different functions that the plasma membrane assure. The course just makes my understanding of cell dynamic very straightforward.

I feel that the delivery is good but the content is not detailed enough, e.g. when talking about splicing, I think it would have helped to talk about what ‘snurps’ are involved and how this relates to initiation.

It's an excellente teacher! She uses easy analogies that you can memorize quickly and gives you a summary of your class (in my case). Greetings from México!

Excellent structure and content. Essential basics for chem and biol.Thank you.

Well organized backed with excellent methods of teaching & illustration. In summary, I found what I want in short period of time.

High yield facts and clear explanation, the fundamental elements and efficient route to master biochem!

I am new to this curriculum, however, I would like the lectures to be longer. I am hopeful that other lectures are much more detailed, e.g. gene regulation/expression. Lecturer is very knowledgeable, clearly.

Thank you very much! Those extraordinarily awesome questions help me better understand the whole thing with details!

I liked very much this course. It's very interesting and The good teachers.

Wow, these two amines are very tricky, thank you very much, Prof. Ahern!

Me gusto mucho porque pude repasar el tema sobre la homeostasis.

I liked the lecture and the diagrams, I can put 5 stars yet because I am unsure how relevant everything is. Pretty basic biochem, but it was a good refresher. The diagrams are helpful.

very bad .. they dont have mycobacterium.. dont purchase the subscription .. these people have fooled us. they dont have anything on mycobacterium tuberculosis

From previewing the course. With absolutely no background in the medical field. I found the course intriguing and thorough. Learning many aspects of the human body within several lectures.

very good, is complicated, but i understand everything, she is a good teacher

I cannot believe I am just now finding this resource during my dedicated Step 1 period. However, I am so glad that I found it now, right at the beginning of Step prep, rather than later. I plan to use this as one of my main resources for the remainder of time up until my exam. I realized while reading First Aid that, although I had known the subjects very well at one point, that my foundation was not as solid as it once was. This is perfect for reviewing and providing the big picture for everything. It's also an amazing resource for providing the "why" and "how" behind all the small factoids written in First Aid which is just what I need. It's so much easier to retain the information when you actually understand what is going on rather than memorizing a 650+ page book of bullet point lists/facts. This is great. I was a huge fan of Boards and Beyond, but I have since ditched that resource and am fully focusing on this one since this seems a lot more comprehensive and better taught (though Dr. Ryan has also done an amazing job too). Thank you guys so much for coming out with such a well thought out and developed and thorough resource. This is going to make board prep so much smoother. If I end up scoring highly on Step 1, I will make sure to write a review on Reddit, SDN, etc raving about Lecturio.

great! Lecture for the professor! Good animation, easy to comprehend!

I love how all these complicated defenitions and ininformation is explained in such a pedagogical way. Many thanks!

the explanation is very clear, the scientific names are pronounced very well and the illustrations are standing out.

I wish all the other professors had her didactics. Pointing clearly the goals of the presentation before and after the lecture helps us to mentally organize the subject.

I agree that it was brief if someone was looking for something more comprehensive. It was sufficient for me as I only required this to understand one lecture slide however not enough questions.

This guy is on top of his game at a ridiculous speed... I can't complain only if all others know their stuff like him there will be less confusion

it is really good ,some hesitation at the beginning but the diagram is very informative ,whopple hypothesis needs more explanation.

The course is informative and up-to-date, which is really important for me. I took my science courses before 2010; now, I’m preparing to take the MCAT. It is an excellent review of content.

Cool. Great examples, Should have showed how the equilibrium of the equation changes once there's acid base disturbance, and how does the compensation is predicted. For me it's much easier than the graphs.

Gooood job LoL and really a good story-maker????Thank you very much! Amazing, very impressive!

Thank you very much!! So funny and interesting! I laughed many times LoL also learned A Loooot!!!

I do not think there can be any simpler explanation of these concepts. Dr. Cornwall takes her time to explain these concepts in a way that they stick with you, and the analogies she uses engrave them into the medulla so that you can relate to the concept. You can't beat this! This is exceptional!!!! Thank you so much!!

First step to refresh and understand different concepts. Highly recommended.

The material covered a wide variety and having a non-science background it is clear and easy to understand.

This guy just knows his stuff, on point even with the speed of his speech he has mastered his slides. I almost got scared with the previous lecture in genetics but he managed to bring me back home. Very knowledgeable keep up the good work and add more clinical correlations.

excellent she is a very good teacher, the grafhics are didactical she explains in a very simple way, i like it

Care for details and passion/curiosity for knowledge are seen in this lecture. I gained a lot from it.

I had to pause the video to rate it! IMO professor Thad is the best teacher! and his voice is magical i could listen to it even if it was audio only! another great course LECTURIO!!!

very well explain and illustrate! The information match perfectly the pictures and the speed of the expositor is flawless.

Thank you very MUCH. I learned a lot. He presents the lectures in a very understandable way. I appreciate him a lot. I became so excited while listening to his presentation. Thank you, thank you, and thank you. God bless you.

I LIKE THE PRESENTATION AND I LEARN . PROFF. USE A SIMPLE AND UNDERSTANDABLE LANGUAGE

Very well explained which makes it easy to understand and memorized.

MBBS student cant get benefit from this lecture. The clear concept needed for a future Doctor about Microbiology.

it's not helpful for the new medical student.lecture should be more prolong and specific,little slow mood.

really thorough explanation - finally i understood the problem with the set point great explanation of the influence that prostaglandin has!

I like the fact that the lectures are detailed and Dr.Cornwall makes it fun and easy to understand.

Very profesional, why is it said that bacterial chromosome has a single origin of replication and eukaryotic multiple origins

The course was well explained. It is confusing subject matter, but she did her best to make it understandable. She is funny, energetic and lively

This is course is still challenging me but i can understand how abstract the concepts are i think i need an in-depth review of course

Thank you Dr. Cornwall, I really think genetics is quite a difficult concept so you are doing your very best, i must admit its very confusing at times i will need go over the concepts again.

It's really helping me getting the basic understanding. And the tips for surviving medical school is worth to try.

I really loved it, because PhD Cornwall made it really easy to understand.

This lecture was excellent in every way, I must say DR. Cornwall is a Pro in intermediate metabolism. I couldn't understand this processes better in medical school than she has made me.

Brilliant. I recommend this course strongly if you want to understand this topic.

Based on explaination. I felt there was some lack of informations. In some area needs to be more profound.

Its really interesting subject made easy by an interesting professor. I'm not sure if that level of details are needed for the USMLE exam as I'm using the USMLE curriculum, if its not needed thats fine it will be for my future knowledge hopefully if i get to keep in my head.

Great lecturer who is knowledgeable about the subject. However the animations in both mitosis and meiosis would have been in motion so the explanations were tuff to follow. overall good attempt. keep up the good job.

he talks very clearly, coherent, easy to follow, i read only the free sections was so nice and clear.

great lecturer who is very knowledgeable about the subject matter, pitch, diction and pace is terrific. keep up the good job.

great lecturer who is very knowledgeable about the subject matter, pitch, diction and pace is terrific. keep up the good job.

It was simply amazing. The knowledge I got exposed to was simply clear cut and delivered by an expert in layman's literature. I am keen to absorb more of Mr. Kevin Ahern's lectures.

The lectures are nice, simple & very well explained. I would definitely recommend this course to my friends!

This instructor makes this course enjoyable, and very easy to understand the materials presented here. I have already informed all my friends who are interested about going to medical schools about lecturio. Lecturio is a blessing to mankind.

Dr Cornwall is wonderful teaching Neuro. I personally love her style of teaching

Great many teaching points given in a well organized and easy pattern. The lecturer is lively with expressions and gestures though initially she appears to be referring down over her notes, but subsequently overcame that hurdle. Her tone and expressions show that she loves teaching. The images and their explanation is superb as well.

I like how Dr. Ahern took his time to explain the topic in an articulate manner. Helped me understand the topic and want to learn it more.

Excellent lectures, you can understand in a few minutes the basics of difficults topics

Well explained she took her time tho but she did it well

El semestre pasado apenas y me di cuenta de todo lo que la enzimas y las reacciones significaban, ahora creo tener una visión mucho ma completa, GRACIAS

Batalle mucho para entnder mis clases pero con estén curso tengo un mejor dominio de el metabolismo y me permitió realizar una presentacion del tema ????

An excellent, brief and up to date piece of information, ideal for quick recall

Good content, I like this course, but this particular class could be a bit clearer

Very easily to follow. The concepts are explained so that one who isn’t familiar with biochem can understand with ease.

The slides and the lector overview we super nice form them only I was able to grasp the content of nutrition. I also liked the metabolic importance of the vitamins and the metabolic processing of alcohol. I really wanna recommend this to my lector of nutrition and those few peers who don't know about lecturio.

Thank you so much Sir for brief description of all topics.

Lectures are good but not enough information. How about genetic replication, metabolism, ....? MISSING!

Well done by the professor with full of transfer sense.

I really enjoyed learning something that I wouldn't have enjoyed otherwise. Thanks a lot for such a great lecturer.

the lectures is shallow; i think that more details are needed. it is ineffectual for the level required from the biochemestry course of the Med University of Florence. cordially gioia

couldnt understand a thing. Please try to use animation to explain better

I thoroughly enjoyed all the videos. Also by listening to these lectures, my uni lectures are making sense to me now. Thank you so much Dr Vincent. You have made my life so much easier now.

Classes have an excellent quality, however there are small mistakes when you´re reffering to some specific molecules such as cAMP and cGMP because in some ocasions, you tend to exchange one with the other in just a few ocassions. Nonetheless, the overall course is excellent, with clear explanations.

Sometimes the lecturer reads some information without explaining what is meant by it. If you can improve that I would be glad.

The lectures are well organised and gives you a basic understanding of viruses and how different types of viruses replicates in the host cell but it doesn't talk about the individual viruses, pathogenesis and the diseases caused by the individual viruses.

He is very good excellent clearly understand the lecture pharmacology aesthetic

The explanation is so basic and explicit, hitting all the important fact that, even illiterates would understand. Great lecture!

Doctor Racaniello gives us great explanations about the different topics of bacterial biology. One of the things that I appreciate the most from his lectures, is the appropiate speed and use of clear language which facilitates the understanding for foreign students such as myself.

How I wish I had this when I first started medical school. The explanations were clear and concise. The use of simple words enable me to understand it well as well as the option to pause at anytime allows further internalization of the facts.

I am having my genetics exam soon and this course was extremely helpful to better understand the information. Thank you !

Recommend this course to any medical students doing pre/clinical Helps with pathways and understanding breakdown.

You can memorize or you can understand. Concepts are yours forever. Memorized lists of facts are gone the very next time you need to cram for another test.

Free trial makes lot of problems in watching the video .... Not properly organised app

u r so good like honestly amazing thank you so much professor

I never would've thought such a complex respiratory concept would be simplified by a bunch of colored garden gnomes. Thanks Dr. Wilson!

Excellent! Well delivered and full of quality information. Totally recommend this course.

Dr. Ahern was very clear and concise. Great lecture. Thank you!

Doctor Ahren. Great explanations and enhances my knowledge in biochemistry, i´d rather reccomend you tu use a lower velocity on your explanations because some of the students are foreigners and they probably may lose the idea. Nevertheless i´m completely satisfied with your video lectures.

Amazing stuff but doesnt differ the exotoxins into the four forms of them.

Simplified the lecture in enzymes and i like how everything was explained in a simple but direct way. :)

I liked the lecture it gave me a brief idea of the concept

I think each lecture is great, but the contents are not enough for USMLE. More precisely, the contents of general principle parts are helpful, but those of detailed exposition parts should be improved to contain more information. For example, You need to provide us for more details about many types of bacteria. The number of kinds of bacteria addressed in this course is small. It's far from enough for USMLE step 1. The same same goes for viruses. The others are favorable.

Amazing lecture and slides explained very well and it was useful to have the slides downloaded.

It is super understandably explained :-) I really enjoy listening to you!

Great teacher !! I was amazed with your way of teaching.. You made one of the most hard subjects look so easy thank you

I learned a lot about cell structure in the most simple and efficient way.

Best pharmacology classes! Love the questions in between the lecture!

It's more efficient than reading the book.Excellent, it's easy to understand!!!

Incomplete information. I'm fascinated with the fact-based approach to the biochemistry of the human body. I like learning about the role that nutrition plays in disease prevention and the overall affects on human health. However, this course appears to still support the outdated views on proper nutrition and nutrition-related disease prevention. I feel that physicians do not get sufficient quality education on nutrition and that corporate interests still play too much of a role in both nutrition studies and nutritional recommendations. Today's healthcare system is more of a "disease care" system, and this profit-centered business approach, specifically with Pharmaceuticals, is doing little good, and in fact, doing a disservice to the overall welfare of the American people.

La doctora Cornwall presenta la información de manera concreta y comprensible. Te permite adquirir fundamentos básicos de nutrición, suficientes para tener un buen desempeño en los exámenes.

Explanations by Dr. Wilson are great. This was a great alternative to review the basic concepts about this topic.

I really wanted to give it 5 stars specially because of the question pertaining to Fick' s law that was included, however the fact that Sir didn' t mention that all forms of diffusion are passive and the word Diffusion itself means being randomised made me give this 4 stars only.
