I really like the Princeton Review Guide to Medical Schools, and found it to be *much* more helpful than the AAMC Med School Admissions Requirements (MSAR), which I know is akin to the Bible for a lot of folk 'round here. The PR book gives you tons more information about student life at each individual school, provides breakdowns of each school's admissions habits/criteria, gives detailed curricula, and info on residency match results. And no, I didn't take a PR course or anything. They just publish a damn good guide.
