You should check out the dedicated USMLE Step 1 forum. However, most people seem to swear by the First Aid book, BRS Path, and BRS Phys. Aside from those, you will find some variation for the other classes. Also, using Kaplan's Qbank is also recommended to practice questions, etc. Check out the USMLE forum, it will have all sorts of info on books and study schedules. Peace.
