I'm in the same boat as you when it comes to AP classes. This year (11th) I took AP History and AP Calc, and next year I'm thinking about AP Bio, AP Lit, and/or AP Physics. I'm taking Anatomy and Government as well.
I vote AP Calc because if you get a 4 or 5 on AP exam some colleges won't require you to take it freshmen year of college. And ALL colleges, despite your major, requires you to take Calc, so you might as well get it done with now.
thats seems like a good schedule, it's a good idea to take harder classes because since many kids take it light during their senior year, colleges will see that you like to challenge yourself.
