funny you mention bc; i'm actually not taking it currently, as im a junior...actually i have a few friends who are juniors who are taking it, but that's because theyre bloody insane.
the first class the teacher says: "i will fail you. the first half of the year you may pass just because i dont want to screw you out of your college admissions. the second half, i will fail you all."
meanwhile, my junior friends in that class are like "oops, we're screwed"
