I used:
-First Aid, of course.
-High Yield Series: Embryo (a bit more than you need, but good to skim and review), gross anatomy (good, but supplement with BRS/Chung Anatomy), neuroanatomy (VERY good--highly recommend), biochem (very good, use in conjunction with First Aid), cell bio (a good review...I used only this book and First Aid, and felt well-prepared), immunology, and behavioral science (a MUST-read. I had TONS of behavioral science on my test, and I picked up a lot of "factoids" from the high-yield book that showed up on my test).
-BRS books: Pathology is a must. I spent a lot of time on the genetic diseases chapter (something we didn't cover well in school, especially the immunologic deficits--and this was hit several times on my "real" exam). I used the Chung Anatomy only to review things I felt I needed to know in more detail than First Aid (but use sparingly. I only had 5-6 anatomy questions, and most of them were clinical). I also thoroughly reviewed Costanzo's BRS physiology, and I think it was worthwhile (I'd used Costanzo for both 1st and 2nd year review, so the book was really familiar to me).
-Lewinson and Jawetz (Microbio and immunology, board review). I personally like this book much more than Microbio Made Ridiculously Simple. I also found that the antibiotics chapter in Ridiculously Simple has some errors. Also, the Lewinson and Jawetz book has a great immuno section, and it's nicely condensed. One caveat--this book is long, and I used it to review only because I'd used it and liked it for microbio classes.
-Lippincott pharm, but only as a supplement to First Aid. You'll be overwhelmed if you try to use the whole book. Someone told me all you need to know is the First Aid pharm, inside and out, and they were right. There was a lot of pharm on my test, but almost all of it I'd seen in First Aid. I also used pharm cards--some people say they're outdated, but I found a lot of them to still be useful--especially for parasympathetic and adrenergic drugs (hit HARD on my test, and I've heard the same from a lot of people).
-Bug Cards. I started using these at the beginning of 2nd year, and it was worthwhile. It would have been much harder had I waited until just before the boards.
My biggest advice: study hard during first and second year. If you don't, there's no way you'll pick up enough information in the few weeks before the boards. It's overwhelming enough as it is! If you keep up with your studies, though, it really IS board "review" and not board "learning for the first time."
Good luck!
(although I was scoring between 70-85% on Qbank, if that helps).
