How hard is AP calculus AB

-how much time do you study each night?
-how hard is the exam? rate(1-10) 1 is the easiest,10 is the hardest.

30 minutes/ night
exam is 7

So depends on what you mean by "hard"

I took it and I thought the exam was hard, BUT it is graded easily.

I believe a large amount of people get 5s due to the easy curve (like 40+%), compared to other tests like AP English, which is around 10%.

Also, I only read the prep book I got from Princeton Review and listened in class.

Dont worry, calculus is easy
