Believe it or not, but I self studied all of Calc AB literally the week before the AP exam. And I was taking 3 other AP's. This goes to show how doable this is. I think I may have pulled off a 5, possibly a 4.
My method: I signed up for the Calc AB course through CTY, but I didn't start it until the week before the exam. I used the class to learn the difficult topics and then used Princeton Review for the rest. Trust me and use PR
. You WILL fail if you don't. Good luck!
