There's AP classes? AP tests are when you take classes in high school for college credits, right?
If I'm thinking of the right thing, I took the English Composition test. I was surprised to find that you were supposed to interpret poetry in a composition test. If there were classes, they probably would have given me a bit of warning, but I managed to squeak by and pass. It was harder than I expected - I wasn't expecting to have to write whole essays and try to figure out poetry.
I dropped out of high school to begin my career as a street prostitute, but I managed to cram in 6 A.P. classes. I made 5's in Biology (I aced the part on reproduction) and American History, 4's in English and Latin-Virgil, and, sadly, I only made 3's in French (the oral killed me, but, really, I'm good at oral, ask anyone) and Chemistry. For the two years I did the high school thing, I was pretty successful and I went to a great high school.
I always thought I had the brains to go back to school, but now, who cares?
