These are the books that I found to be most useful:
Primary books to memorize cover to cover: First aid and step up (revised edition)
Books to read cover to cover and answer questions from: BRS Physio and BRS Pathology, high yield behavior science
Books to read as a reference (ie not cover to cover, use prn (as needed
): high yield neuroanatomy, high yield gross anatomy (if you skip these two book, just memorize the parts in First aid about these two subjects and you will probably do just as well); high yield embryology (1st edition, try and purchase it from an upperclassman, the 2nd edition has too much info), Lippincott Biochemistry, Lipincott Pharmacology
Kaplan Q bank is essential for your studying. I would do every question and read the explanations as you do them. Other resources that I had but didn't use but other people used with ok reviews are the UCV series, BSS, and NMS for the USMLE step 1.
Make yourself a schedule based on reviewing first aid and step up everyday and you should do alright.
