For the general chemistry, I would suggest using a textbook because many of the review books I have seen are incomplete.
For physics, the Princeton Review's Physical Sciences Review is very good. Has shortcuts for questions and explains everything very well. Other textbooks are calculus intensive and spend a lot of time proving theories and equations, which is actually useless for the mcat.
For biology, use textbooks. Again, many review books out there are incomplete. For example, some of the books dont discuss molecular bio and biochem in depth. And last year, they had questions on retrotransposons and background familiarity could have helped.
For Genetics: usually the review books are complete
For physiology: Vander's Physiology 9th Edition
For Molecular Bio and Biochem: Garrett and Grishams
For Cell bio: usually the review books are complete
For the Organic Chemistry, many people suggest using Kaplan's materials on it. I think Kaplan has good passages and questions for the organic. However, you will be expected to be familiar with every reaction in the course, so I suggest using an organic textbook.
For the verbal: Everyone says Examkrackers is the best...I might have to agree with that.
If you are done with everything, you can try out MCAT 45...its not really a workbook, but an advanced strategy book. Its for people who have really practiced a lot of MCAT. It does have very few passages...but they are geared towards strategy and the passages are ridculiously hard!!!
it also has some of those verbal "killer" passages if want to try.
Then do the practice tests...all the AAMC ones, try to get ur hands on the TPR and Kaplan tests too.
