AP classes or AP National Exam that is given on certain days in April? AP classes are graded by normal standards but credit is only given it u get a 5 on the AP exam in that subject. Harvard gives u credit only for a 5.He went to a high end university and had 5’s on all of his AP classes but you simply don’t get credit for anything you don’t take there.
They had exams before they started to make sure they didn’t have to take remedial calculus lol. I had no clue proof calculus was a thing until I looked at his textbook.
Sorry for the sideways chat from the OP.
