I have a used set of Princeton Review MCAT books. They are from 2006, but I used it for this year's MCATs and they did a great job of preparing me. (Hence, the selling). There's a moderate amount of highlighting in the review books, which I think are the best around, they hit all the areas MCAT covered.

About half of the practice problems are done, but you are insane if you think you need all 50E6 questions. Again, the content hasn't changed and the questions haven't changed, I can vouch for that. Asking 100 OBO.

The set has like 7-8 items including an excellent Physical Sciences review book, Biological Sciences review book, and Verbal Review book. Also comes with Physical Sciences Workbook, Biological Sciences Workbook, and complete sample tests in the old, written format (better for practice, longer).

Good Luck!
