FWIW, I did 5, 2 and 5 points better on AAMC's 7,8,9, respectively, than I did on the April Admin........don't take anything for granted and bust your a$$ to understand the material on all AAMC tests, even the earlier ones (I didn't take the earlier ones because I thought like you). Now I get the chance to take 3-6 before the August administration.
