<p>Hi, I'm a freshman and I want to purchase some books to start studying with. I'll probably remain a self studier until it's time to take the tests. Any recommendations? Also- for my AP exams, could I use the subject test books? Thanks so much!</p>

PSAT - none or blue book
AP classes - books dedicated to AP (not kaplan IMO)
