Any advice with AP Chemistry?

I'm taking AP Biology this year, and I fairly enjoy it. I'm getting an A in the class, and believe me, it took a hell lot of suffering for that grade, especially with AP Euro and sports.

I'm planning on taking AP Chemistry next year, and all I constantly hear about that class are pretty bad. Besides being told I'll die in that class, I'm worrying about how I'll actually fare.

Math is not an impossible subject for me- I do fairly well in mathematic classes if I just look over my notes and homework. I'm in Algebra II this year. But, I'm not a total math genius- I've gotten some C's on tests and quizzes before.

Obviously, Chem involves a lot of math. I'm not too good, nor am I too bad at math. I have no idea how I might do.

Help?
I have good work ethics and am very determined to do well in this class. Motivation is the key to everything I do.

But do I have to be great at math to do well in the class and on the AP exam? I love biology, and enjoy math, but what does that say?
Many thanks to those who answered!
