General Principles of Foundational Sciences

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.

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

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

i have never seen such an outstanding Lecture, really appreciable. Dr.Vincent words just penetrated my heart. What i like is, his way of presentation is marvelous with good pace . even non science(Non-medical ) students can understand without any trouble.

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.

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.

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

Very easy to understand difficult bacterial's names and functions. Very well explained and resumed, thank you so much.

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.

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

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.

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.

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!

great lecture ,great professor! all the lectures are very much cover all the important concepts . just need more videos to cover the other bacteria like klebsiella,spirochetes,syphilis and the zoonotic bacteria .

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.

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.

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

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).

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.

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 was very clear and easy to follow. Thank you for these lectures.

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.

great presentation and eloquence. the lectures are well done and easy to understand. great information, and would highly recommend it.

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.

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.

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.

Prof. Racaniello makes learning of microbiology an awesome experience! It's pretty fun to watch his videos.

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.

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.

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.

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

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 like this professor way of teaching, good explanation, good tables, good rhythm speaking

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 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!

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

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.

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

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

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.

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.

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

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

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!

Great help to get through my first year in medschool.

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

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

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

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.

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.

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.

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

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

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

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.

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.

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!!!

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.

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.

Professor Racaniello gives very precise and concise lectures. Excellent job!

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.

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.

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

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.

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

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

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.

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

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!

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.

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.

I rate it with five stars because the presentation is dynamic and interesting, I like the way she explains the topics, with goos clinical correlations. I would recommend it to other medical students and more on to international medical students, because it is easy to get familiar with the terminology

It is too much Helping. It is Awesome and helpful

Essential key points in short way but enough to understand the topic properly .

The topics r taught soooo easily that,u can understand even if with a little knowledge...

i like ij]t very much i love it thank you my name is george

Hi everyone. This is an excellent tool to remember everything i went trough when I was in second and third year of Medicine. I appreciate that in all of your lectures, there is a relaxed enviroment and the speed of your explanations is really appropiate for the individuals with a native language different from english. In my case being spanish.

I finally understood why keto diet is so effective :) Thank you Dr. Kevin!

i rate this to support u and encourage u too go ahead fabelous job thnx

First time I get to understand the various confusing genomes. wonderful

very brief and only touches the superficial parts of ssDNA genomes

Everything makes a lot more sense now and the visual aids are also very helpful. Thanks!

All Dr. Wilson's lectures are great. Good contents presented in a clear and interesting manner.

Education is a performing art; less reading more personality. She has great potential.

The lecture were short and concise and were just thesame as what I needed to learn.

The lecturer uses great analogies to make concepts easier to understand.

amazing comprehensive lecture. never had such clear idea about embrology.

This lecture was very educational, and well organised, moving from the basics to the complicated topics, explaining every topic step by step.

Explains everything extremely clearly and made all of the processes easy to understand. This was a great lecture series!

it's amazing the example with the gnoms thank you !! easy to learn

I would like have a tag on videos that have been completed, indicating watched status.Like read and unread mails.It would be helpful in keeping track of what has been completed.For example when I use bookmacher too, the search results would indicate what has been watched earlier.

Every topic was clearly explained and I could understand them very well.

These lectures are good , but it needs improvement it should be more in details , and the actions are not mentioned in its orders for example first of all initiation then elongation finally termination ..

The lecture was very intriguing! Dr. Ahern is so well articulated!

I love his courses! Really interesting and informative! Thank you for this awesome lecture.

I don't waste my time going to any biochemistry lectures at my medical school because I know that Dr Cornwall explains all of the content more clearly, in more depth, in less time. I always finish her lectures excited for the next one!

Brilliant! I have always found these topics extremely confusing at medical school, but Dr Cornwall is able to explain them in such a way that they seem straight forward and easy. This certainly replaces lectures for me! If anybody is unsure about trying this course, they should definitely try it! Dr Cornwall is the best biochemistry lecturer I have seen!

Dr. Cornwall hesitates a lot, and seems unprepared and unsure. Make people feel like she is reading the material and even not familiar with the reading materials. It is really confusing.

Very helpful on understanding the basics of the repair mechanisms.

The Good: Lecture: 5/5 Amazing Lecture! I learned a lot! The Not so good: Quiz:2/5 Only 1 question....and was not as specific as I would like it to have been. Perhaps consider having at least 50% of the terms discussed included in the Quiz.

Very good correlation with important diseases. I had a better understanding on the crucial areas of aging that is related to patients’ diseases.

Only been using this site a few days. However I am already impressed by your material. Perfect execution of rhetorical techniques. Especially placing things in context with vivid verbal imagery.

A great lecture. I am a high school student and i struggle with biology. I get a better explanation from your lectures and I am not even a native English speaker. Thank you so much!

the lecture is good it educates on how bichemistry is related to other fields in life

I find his lectures natural and easy to follow. He tells us areas we must take note of and what we absolutely need to remember. Complicated aspects are broken down and summarised simply. Will continue to listen to these lectures.

the lecturer is very good in lecturing, i understand very well morethan in the class hall

Thank you so much for beautifully explaining every single basic detail in chemistry. The modules covered up the required topics from the scratch to strengthen my basics.

Thank you Dr Ahern! Thanks to your clear and nice explanations With integrations I am finally starting to understand Biochem! You make difficult things look so simple and enhances the importance and intelligence of mother nature in our human bodies

I think this course is really informative, though I would like some more details in subjects like RTKs and G coupled proteins. And also please add English subtitles to this course! I'm not native and I found it hard to keep up!

Very up to date information about prions. Professor Racaniello makes every lecture interesting.

The courses are very concisely presented, it is really useful for preping for an exam

I liked that she really knows what she is talking about and is able to explain complicated things with examples from everyday life.

Need more details Need to go slower But overall not bad

It is very clearly and enthusiastically explained. You make Biochem easy to understand.

I really could understand this lecture easily. Even the mid time of lecture gives questions are more helpful for interacting with it.

As a medical student I found this series of lectures on enzymes extremely clarifying. Dr Ahern is a great lecturer. Thank you so much.

Very precise and concise, highly recommended to all my friends and colleagues

Thank you Dr.Thad Wilson for this wonderful lectures ! Easy to understand without missing the details of the subjects !

Excellent professor. Bugs made interesting! The table in the last lecture was very useful.

The lecturer is very good at getting biochemistry across. Well explained and understandable up and until here.

I had no background in microbiology and this lecture helped me a lot with closing the gap. Thank you

Very passionate lectures. I learned a lot about the basics of virus

He is very passionate lecturer. His lecture is very engaging and interesting. Thanks for your lecture

Needs more substance. This was barely long enough to be an introduction.

Very interesting. Maybe ratio of aminoacid tryptophan metabolized to niacin and niacin consumed with food is good to mention. B6 can be pyridoxine or pyridoxal?

This lecture and the one before are not so well explained. The clamp loader part and the process of semi discontinuous replication need more in depth explanation

Professor Dr. Kevin Ahern is very clear in presenting. Love the short but very informative lectures. Would recommend to everyone, those with or without biochemistry understanding. Thank you very much Professor and Thanks to the maker of Lecturio.

it was really helpful,but a bit fast, good details and nice explaining

5 STARS TO DR SHUKLE Because 1. He speaks clear American English. 2. Lectures are very visual, concise and substantial. 3. He behaves and dresses very professionally. 5. You learn a lot in little time with quizzes between lectures. 6. It's so much fun and easy.

Fantastic lecture, just the amount of information I needed to cover and retain the topic.

perfect !! i really liked the intro, but there is still some problem with questions..

the lecture could be better it was hard to understand all the curves.. and the answer for the question was not so clear

Easy to understand due to clear explanation and concisely told

It helps very much. Thank You. I will share with my friends.

Good clear concept review. Could use more specifics regarding cyclin and cdks.

I understood perfectly the concepts the way he explained them. He makes it ease to grasp

hello, My name is Oscass Jimmy. I love your product and would like to kindly request you to upload us better organised notes and if possible, let us have access to the referenced textbooks you have on this site.

few things are missing like discoiling of histone protien and a sentence is not repeates

Very concisely put, I love the lectures, very helpful indeed. Now all I need to do is work my ass off to get the dollars to pay for this awesome lecture. Thank you Lecturio!

wonderful lecture by Dr Thad Wilson...........i got a glimpse into the minute details of the topic as a whole..........thank u sir..............

wonderful lecture by Dr Thad Wilson.....thanks to him,,,,,,,,,,,thanks to lecturio.................the topic is well understood.............

nice and excellent lecture ..................found it easy to understand...............................thanks to Dr Thad Wilson for sharing his expertise and knowledge..............................also thank u lecturio

The course is not sufficient in clinical settings. Very theory into research , yet less in diagnosing . Good for a student into research PhD, yet not for students doing medical degree or USMLE.

somethings said are not so clear eventhough we can refer books............... In the quiz the na+ k+ atp ase is said to be p type pump..................... but in the lecture it says it is a v type pump........................ i want to know which is right..............................

i think the topics of the lecture is not easy and it has a lot of new terms those need to be clarified more clearly

Structurally complete, however, relatively outdated. Enough for medical study purposes.

Very good keeps on track with my textbook. Taking Intro Bio

It is really so good thing to take more information and I like so much the way of the explain for the teacher thank you so much for this helping for students

Các b?n Vi?t Nam nên dùng app tuy?t v?i này ?? ôn luy?n ki?n th?c y h?c

I like the way that the AA are presented by a table between essentiel and non essential. I will use it for my memorizing process.

Great/clear explanation, definitely recommend to students. For those that complained, please describe what's needed to be explained, or just keep your pie hole closed. Being ambiguous is pointless.

I disagree with the comment below. I think he is a very good lecturer. Clear and concise. Yes, he does he have his unique gestures and tones, but so what? It's just different from the traditional, not wrong or anything. I found his lecture interesting. I don't think he was mocking anyone.

great lecture! I still feel the need to fill in the gaps but it has given me an overview of gene regulation

Dr Racaniello, is good. Easy to understand, good content. This course is hitting all topics in my med school course.

It's very clearly explained and very useful for my studies. I would like it to be a bit more detailed but not too difficult.

l am a pre-med student and after watching this lecture I decided I was definitely subscribing! Everything was explained clearly and I understood the concept completely.

Too vague; I got the same basic information/presentation out of lecture. I was hoping for more clarification in these videos on topics like dose-response curves.

A like this course and lecterio helps me for understanding the concept of this course easily. Really lecturio is place where medical student gets his needed resources. So thanks and keep going that great work for medical

The use of the acid-base box made this topic so easy Thanks

Presentation could be a lot better, teacher continues to show lack of preparation as the video went on, not engaging to the viewers.

It was very helpful as I am a visual learner and I was able to add more material to my notes. Plus, I enjoyed that she simplified everything.

Kevin Ahren explained the part very well. I liked the way he explaining this part. I am from business back ground.

Dr Raj makes everything more simple, it is a good effort you make to teach

This course is very well organized. I am doing all my best to learn from it as much as I can.

Dr Georgina is amazing. Thank you for making all these difficult concepts easier for us.

Very nice and great lecture! The questions were very help recall the main points. Thanks!

i like this lecture. way of representing and explaining is quiet good.

Very well done job. Dr. Vincent is excellent. If someone does not have a better understanding of basic and clinical microbiology is not his fault. He has done all his best to facilitate the concepts in a very clear manner so that everyone can understand. Good job Dr. Vincent.

Finally understood the anion gap!! Thank you! The chart with the green red and blue midgets I found very funny and creative and even if I took this course several months ago, I still remember perfectly the chart because of them!

Dr. Vincent Racantello is a wonderful facilitator. His teaching is very connected to the concepts of the topics. His explanations are very clear. He even takes time to recap when it is necessary so that the learner can stay on right task. I wish I had more available time to invest in his teaching. He really inspires me to push myself a little bit more. Thanks again

This professor is a very knowledgeable professor. Overall, he is excellent.

Dr. Racaniello is a very good professor. He takes all his time to ensure that his students understand the concepts of the topics. All his feedbacks and examples are very relevant.

He is a very good lecturer and great facilitator of microbiology.

Very nice but there's some need of detailed explanation and then it would be perfect

Excellent lecture. Loved that it was succinct and to the point.

Thank you so much Dr Kevin, this lecture series are the best that I have seen so far and explain very well, simple and practical a very complicated topic.

On the slide about respiratory compensation for metabolic acidosis, the compensation slope with decrease Pco2 level has a PCO2 value of 60 which should be 20. Becauase in respiratory Compensation for MA PCO2 slightly decreases That is just a typo, but can been confusing The lecture itself is very good

he is so good ... I am very thankful to you sir !!

it was perfect and describe a part of endocrine system very well.

A great, insightful lecturer. A Prof. at the top of his game. Miss his long hair though (checkout his youtube site)!

I'd like if you add a specific explanation about the main types of viruses and diseases caused by them like you did with fungi, parassites and bacteria

Very good, interesting and memorable lectures. Dr Raj presents complex topics in such a light way that makes it enjoyable to follow.

Awesome job, I wish you were my teacher at my university! So clear!

great and well made, I'd like if you add some quiz even in this section!

Couple of mistakes were made and he sounds as if he is mocking the audience

Very well made, all the important thinghs to say are dealt.

What I loved the most about this lecture was how Dr. Cornwall actually took her time to explain the concepts discussed, and even used simple analogies to ensure that the information was easier to digest. This is something you find lacking in many professional lectures. Thanks again Dr. Cornwall!

Great but I'd like more type of bacteria and how to treat them

Perfect, easy to follow and understand. I would be appreciated if there are more topics about treatment.

I loved the whole course! I finally could understand a topic that is so frustrating for me to understand and also remember in time! Dr Tad is an awesome lecturer! I lo ve the way he explains everything

The material as presented is easy to follow and comprehend

Each A/B topic is discussed in a straight forward manner. Teaching aids, such as the use of the "Gnomes", makes the material more digestible, as well as for later recall.

thank you very much, nice lecture, sounds great, well presented

They were well described lectures and the examples used were easy to understand.

The clarity of the information being delivered is extremely satisfactory! I enjoyed watching this lecture.

It was very clear and explained well- the subject itself is usually hard to explain

Dr. Cornwall is really quite good. She mispeaks occasionally, but overall is credible and fun to listen to.

Very informative and simplistic in delivery. I eagerly look forward to the questions from this subject during the exams.

Thank you dr. Georgina Cornwall! Everything was perfectly understood with your lecture!

She spends half an hour explaining the steps of meiosis and doesn't even get into details... I'm not sure how she can manage to explain such simple topics in such a long time (it's half a movie time, for God's sake!). She should base her lectures on Molecular Biology of the Cell, by Bruce Alberts et al., AT A MINIMUM. Lecturio has many excelling lecturers; unfortunately, Dr. Cornwall is not one of them.

good good good pronunciation good good good pronunciation good good good pronunciation

Great job It was very useful the video.Thanks so much

Stunning! Explanations are simple and very interesting, wish you all the best professor ????

excellent work by professor to make biochemistry understandable for all

Thanks Dr. Kevin Ahern. Believe me when I say that I have a teacher who just read his lectures. I think that Biochemistry is a hard subject and difficult to understand because most of the things are just known perfectly reactions and structures. But your lectures have something else. I take some notes and it's easier for me to study the subject. Before I started with Lecturio most of my subjects I didn't know how to study. There is only one thing that I would like to suggest. I would like to know some facilities that teachers and students use for know the structures.

Lecture was well organized and covered the appropriate level for this topic.

I like the Lecture it explain many things but there are very important thinks haven't been explained like how to knockout some genes by using shRNA or siRNA. I know that you explain CRSPR which is the greatest method ever . But I think is necessary to talk about shRNA, siRNA and what the advantage and disadvantag because everyday in school we here about them and I think they need to coverd in this lecture. Thanks

Thank you Dr. Kevin Ahern!!! Sometimes you speak so fast, but these time was perfect :)

Easy to learn using the box. I always struggled with this, even on my board exam. This box and explanation made it much easier for me as a visual learner.

Don't replace her. Good OVERVIEW/REVIEW of the material at hand. Her pace is good. Her voice and expression and everything else is dynamic and engaging.

I liked this lecture very much because it's helping me in year 7 right now in my science assignment!

The professor was very clear and his tone was lively :)

Very good teacher! Funny! Great job. I can spend all they long listening to him.

Please replace her. Explanation is very poor, she hesitate a lot, and seems unprepared and unsure. It is confusing and in comparison to a lot of lecturers you have here, the standard is incredibly low!

I found this course to be very helpful to organize my knowledge about this topic. It also clarified to me some concepts that I had not fully understood in lectures.

Great insights and teaching experience. All medical students need this website to improve their scores, take state exams, and improve their performances. I like this course. Makes me to develop more likeness because of the simple and forthright ppresentation, 100%.

Very clear and concise. Information broken down well good review

Dr. Ahern is a fabulous instructor. He goes into just enough detail on all the important content and pathways, bringing everything into a more holistic view of biochemistry. A+!!!!

This video was easy to understand. I appreciated how everything was stated in a simple manner. This allowed me to grasp the concept without confusing me. Keep up the good work.

Your lectures are exceptional, it makes reading the books much easier. Thank you

Covers B vitamins and Fat soluble. Pretty good. Lacks Certain vitamins: Zinc, Fe etc. Loved the nAKED mnemonic!

The verbal language used is very good to understand and interactive. The diagrams used makes the explanation clearer to learn.

I'm enjoying Lecturio, the videos and follow up questions are ideal way to learn, the speakers excellent. I've spent many hours on You Tube hoping to fine something like this. I also saw Lecturio, is on You Tube and have subscribed yesterday having watched the Nutrition video and Biochemistry, also bought some eBooks that was mentioned in biography that I'm sure I will also enjoy. Thank you!

I really enjoyed this tutorial and did fairly well on the questions. Georgina Cornwall, PhD is joy to listen to and easy to learn from.

I was impressed by the knowledge of the professor. However, the very short length of each lecture was disturbing and distracting.

I like too much,plz make more high yelid questions with each topics,i appreciate it.

Carlo makes the content interesting and manageable with intonation and examples.

this guy so good only amazing so much only omg nice nice

Simple and easy to understand! Covers only what really matters!!!

Good lecturer, though compared to common youtube lectures, most of the material is covered too superficially to really retain much, although the gnome chart was helpful for myself. Future lectures could give just a bit more detail to help the bigger picture ideas stick.

Great professor, great explanations. This video was like a summary of important parts.

very good flow of the concepts... looking forward to other lectures!

it was very good lecture it will help me in my med biochem class thanku

This lectures goes through the important prion diseases. It focuses a lot on statistics making the lecture a littler longer that needed. Overall a good lecture if you're not too busy in your studying

This lecture was very organized by introduction and then going into detail with the most important fungi. Made it easy to approach and easy to jump back and forward in lecture if you had a part you wanted to see again

Great breakdown of these biologically important macromolecules. Amazing detail on presenting each macromolecule and distinguishing polymers, monomers and non polymers.

She is very detailed but yet not overwhelming with the lecture. It's been great help on my bio knowledge.

Not very hard to understand, sometimes a bit too "shallow". However most often very good. Even great.

The visual effects are very good and encouraging. I would definitely recommend it to my colleagues

The professor was very knowledgeable and presented the information in a clear and concise manner

Very good course!!

very clear and eazy to understand reccomended to whoever needs to study phisiology

It was very informational , I mean too much statistics about the history. Its really good for a class. But its bit TIME CONSUMING for some one running against time. One should be able to to hit guess the key points for revision. Im sorry, but this is my honest opinion.

blue ,red gnomes ,suoer ,really good lecture,clarified,simplified,nice

covers everything essential, good overview, easy to follow, relevant info

Great content. Very intelligent and elaborate lecturer. However, Dr. Raj sounds very arrogant, particularly when he delivers condescending remarks.

The acid base box helped me alot and the lecturer is brilliant

This is the basic of physiology , and it is very nicely explainded.

From what I understand, we advise patients taking Coumdain to AVOID eating vitamin K rich foods because it will counteract the effect of the drug.

The Dr Georgina did it very well she know detail about the subject matter andinet did not express about her and execelentroll model for me!

this Professor is really an encouraging one, he knows how to contact with his students, he has a deep knowledge, it is my first time to encounter this type of unbelievable professor.. more power Professor Kevin Ahern, from Philippines Honeylette Tayong :) thank you so much sir I really learned a lot from you, and aside from that you really motivated me to study deeper than I can ;)

It doesn't have any material about bacterial classification , bacteriophage , antibiotics , bacterial resistance to chemotherapy ....

Very good explanation and notes and diagrams. Dr has good quality teaching .

I like the way the instructor presents the material , and the examples she uses.

The lecture covered everything I needed to know for my upcoming test. I feel so much more prepared now!

Dr. Cornwall is a good teacher. However the topics move quickly. This is great for biology majors needing a refresher. But for me it is helpful to take a second to restate an important concept or give context on what this process will impact in the future lessons. Helps the listener to remember it when you give it some context.

Dr. Wilson does an excellent job in breaking down concepts of acid-base balance in the body and making it plain. He also provides some additional tricks/tools that you may not get in your regular lectures, but will definitely help on an exam. These lectures are top notch, just excellent!

Seriously gifted biochem lecturer. One of the best on here in my opinion. He explains everything so clearly. Lectures are organized and images are really helpful!

Well, I love the way Dr. G explains, however, the lecture on cell control wasn't the best and needed more explanations and needed to be more simplified . I put five stars because Dr. G has helped me a lot and made Biology a fun course.

This course really helped me understand the cellular structure, I learnt more from one of the 20 minute lectures, than I did in a 3 hour lecture at university, so these really help!

Like the material and subjects good review of subjects look forward to seeing more

Good and clear explanation, Dr. G makes it fun to learn biology.

not much details. its like a lecture for non medical students.

Lectures are well presented. however, this does not completely cover medical microbiolgy syllabus necessary to sit examinations for medical students

I really love his lectures!!! Profesor Racaniello is so funny and explains everything so carefully that I get so interested in every single video. Thank you!!!

In this Nutrition course, Dr. Cornwall elaborates some basic nutritional principles that are essential for any student of Human physiology to understand. The way she presents the information is in much greater detail than what I was exposed to in the small Nutrition course held in Medical school. I particularly liked learning about the Mifflin-St. Jeor Formula for calculating Basal Metabolic Rate (BMR); it literally changed the way I look at food!

Excellent course! Whether you want to review biochemistry for a Board/National exam, or you are looking for help with a Biochemistry course. Professor Ahern details the fundamental aspects of biochemistry in a way that will make the importance of the many unseen molecules and processes stand out in all of their relevant glory!

The program was to elementary in nature and not deep enough. Sections on pregnancy nutrition was very superficial

The professor has a very clear explanation and teaches in a really dynamic way. The only negative thing about the course is that it's missing some essential biochemistry topics for graduation level like the citric acid cycle

Very good explnation ! very easy to understand. I like Acide-Base toolbox. Many thanks :)

It's the best. I really love how the doctor explains the concepts with simplicity. Biochemistry became much easier to understand. If it included clinical cases it would have been better.

great, clear and fruitful intro to physiology course. I'm excited to move ahead.

The explanation given by Sir is very easy to understand and I able to remember for a long time.

Some parts that the instructor was going through were not gone into depth when they should have and some parts should have their own video.

Dr. Wilson is very clear slow enough yet very focused and has concern with the understanding of the learner. He is super and goes to demonstrate as an example that fast-talking is not necessarily better.

Just an introductory lecture on any course enkindles a burning zeal to learn more. It is a perfect review lecture on the go and a better way to have fun while learning. A perfect definition of concise learning in a limited period.

I like it a lot. Good review. The slides for mitosis is the wrong one, ie different lecture notes

It helped me understand the concepts. I suggest you to try it too.

I like this course ,well explained it does cover a lot . It really helped me to get a good mark and information

Outstanding overview of general principles. Should be model for all lectures.

Impressed by the knowledge of the presenter. However, had a feeling that she was asked to push/rush through some of the concepts in minimum possible hrs. Seems like some concepts needed more time to explain. Overall, I loved this series.

Well organized. Unlike some other courses the quiz questions come after the instructor has mentioned the subject.

Never thought I would enjoy listening and learning about microbes so much that I do when Im listening to and taking notes on these lectures..

Very detailed professionally done and covers all the bases including pathogenesis and epidemiology

Starting Biochemistry in the Fall and a little nervous..so I decided to brush up with self-paced lectures on Lecturio. Prof Ahern is amazing! His lectures make it easy to remember and the quizzes in each module force me to look up answers. So this is fantastic for those whose like to teach themselves. I also downloaded Biochemistry free and Easy and it complements the course nicely.

Accurate, slow enough to understand, and he gives concrete examples that clarify each concept. Keep it coming.

I'm starting medical school on August 7th. I'm anticipating some material I'll be trained on in advance.

Learned few new things which i did not knew before. Thanks Dr. Wilson

Great information! Easily to understand and covers a lot of necessary content, thanks Prof. Wilson

I was going to cancel my subscription as I felt the material did not relate to whats high yield for USMLE step one exam. Watching this lecture renewed my interest in the lecture series.

Excellent explanation! The graphics are great and the professor is amazing.

Lectures themselves are very good and very comprehensive and detailed. It would be useful to know how much of the specifics of biochemistry are likely to be examined in board exams...I was under the impression board exams are leaning towards understanding concepts rather than specifics such as the mathematics/calculation of enzymes activity.

This is fun. I wish they were an accredited school. But they are good for prep.
