A course that although it claims to be about the world, is really all about China and Japan. The class is as good as the teachers make it. The test, on the other hand, is about how many essays you can write in the shortest time period.
If you want to do good, study general topics, not fact-for-fact. I did this and got a 5 on the AP exam. You do not need to be a nerd to pass this exam, nor spend all your time studying, i spent 30 mins every few days starting in April.
I took AP US History and got a 5, then had to take the crappy New York Regents still.
