I prep the same way that cupatee does. I don't take a test until i am pushing an 80 percentile on the practice test. It doesn't really take very much more time, and it seems to pay off. I just passed micro using instant cert and the ap micro/macro book by princeton review. (btw instantcert didn't seem to cover marginal social cost in the flashcards, good to know.)
