My main study book is First Aid, since I have spent the last year and a half writing everything in it that our profs said will probably be on boards. As far as extra references, here is what I am using:
Physiology: BRS (blue book)
Pathology: High Yield and Pathophys for Boards and Wards; Robbins Companion for the questions; Webpath for pics
Micro: Clinical Micro Made Redicuously Simple (awesome book)
Anatomy: High Yield
Embryo: High Yield
Pharm: Pharm Recall and Katzung Board Review
OPP: Simmons and Savarese
Questions: USMLEasy website, Qbank for USMLE and COMLEX, Board Simulator, and whatever else I can get my hands on
I have three more days for path and then biochem and behavior sciences and I will be done. Then try to get through First Aid two more times, read USMLE Secrets, and do questions the rest of the time
Hopefully that will be suffice.
