I used First Aid (not a fan), BRS Phys, BRS Pharm, Micro Made Ridiculously Simple, Goljan Pathology book (first 7 or 8 chapters). Maybe some other things too, but I can't remember now.
I used: first aid, BRS physio, micro made ridiculously simple, lange pharm flashcards. Everything else I used class notes and school board review notes. I actually got a few gross anatomy questions correct by flipping through netters atlas the night before the exam.
Everyone will be different in how much they have to study. I would reserve 2 months studying if possible. You don't want to fail that exam. If you put in the proper amount of (quality) studying I promise you will not fail. If you blow it off until last minute you could easily fail.
