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.
