Everything is organized and presented in an amazingly digestible fashion. My only critique of osmosis is that it wasn't marketed better. I've been slogging through endless outside resources throughout my first 1.5 years of med school, but since I found osmosis this has basically been the only one I've used for learning new information/reviewing old info and I've felt it has been completely comprehensive for Step 1 material. Wish I would've found it sooner, but will continue to use this and encourage classmates as well--hoping for the future where students don't have to spend $200,000 for useless phd lectures and can just use something like this. Worth every penny
