I took AP Calculus this year (this is my 5th math class). I got a 64%(2nd quarter), 58.9 (3rd quarter), and 49(4th quarter). I have high grades in all my other classes, and I take mostly all AP course. The quarter grades were solely based on a couple homework assignments and one or two tests. Due to the low math grades, my GPA is not quite a 3.0. It is around 78-79%. Which is 2.8~2.9 (I believe).
