A division of math that requires much writing and analytical thought. Taken by AP nerds, those hellbent on going to the 'best' colleges, or by those with a masochistic streak. Can be taken in place of Caluculus, or, for those who really enjoy self-punishment, concurrently. Mostly taken by seniors.
I'm taking Statistics AP this year because I don't feel like taking Calc AP, but my year wouldn't be hellish enough without it.
