I was wondering which you guys/gals think are the toughest. I've taken Kaplan and PR so far (won't start the AAMC for several weeks yet). Thus far the PR has been the toughest for me. I took a PR test today and got 10V 9P 8B, which is 3-4 points lower than on the Kaplan tests I've been taking. It could have someting to do with the fact that I use Kaplan review materials to study by. Hmmm?
