I am studying for the AP BC Calculus Exam and I know about the free response questions from AP Central, and the Multiple Choice Collection. I was wondering if anyone here knew of where to obtain more problems? At least a collection of problems similar to those that appear on the BC Exam.
I realize this is not a question about an actual math question, but I don't feel very confident in my math ability so I want more problems to solve.
Ps. I don't have alot of cash, so I can't afford to buy barron's books or any test prep books. The local libaray doesn't have any -someone check the book out but never returned it, and the book store doesn't like it when you just sit there working out problems and you don't buy the book.
