So I'm studying calculus on my own, independently. I'm a junior in high school, and I'm getting help from my Physics teacher when I need help. I bought this book https://www.amazon.com/Calculus-James-Stewart/dp/0534359493/ref=ed_oe_h" and it's great. I've learned a lot from it so far and haven't had any problems with the problems... So if I decide to take the AP Calculus exam, which I probably will, which one do I need to take... Calculus AB or BC? Thanks... Sorry if this is in the wrong place.
