I would have to agree with some above posters... I wish I had left more time for practice tests and timed each of them. Also I spent money on some books I didn't end up using, like the Gold Standard MCAT book. I think if I did it over again I would buy all the AAMC tests, The MCAT Physics Book, and maybe either EK bio, chem, orgo, or just the big blue Kaplan book. Go over the material, maybe two weeks per subject, then spend a month doing practice tests and going back over questions and reviewing material. That would be about three months of prep, which I feel is about the average.
