Other surprising statistics (to me, anyway):
% of students receiving a 5 on the AP English Language exam: 9.2%
% of students receiving a 5 on the AP English Literature exam: 7.0%
% of students receiving a 5 on the AP U.S. Gov't and Politics exam: 6.0%
I took the AP English Lang exam last year and received a 5
I didn't think it was too bad, although a lot of my classmates seemed to garner 4s, with only a few other 5's scattered here and there...
I also took the AP U.S. Gov't exam and received a 5 on that too, but that was during sophomore year; even then, however, I am shocked at the low percentage of people receiving 5's on the government exam. At my school AP NSL (national/state/local government), as it is known, has an infamous rep for being the easiest AP class.
I'm currently taking the AP Lit class and will take the exam this May. Hopefully I will emerge with a 5 in the end
