<p>I just started my school year 3 weeks ago and I'm fine in all my ap's except apush. I got a high D on the first two quizzes and failed our first unit test. I've never done this terrible and im especially surprised since I studied my butt off for these tests. We still have 4 quizzes and 2 tests scheduled for first quarter so I can still bring it up to an A, but I think I need a review book as my teacher uses ap style questions. My friend gave me her old Barrons book but I heard its not that good. Ive also ben offered amsco , any pointers?</p>
