Sr. S took AB jr. year; 4 on AP test. Because he wanted to do something with math in college, he took BC Sr. yr. He gets good grades in class, but it also turns out his teacher is scaling the tests. His college requires a placement test. My guess is that he’ll take credit for first semester calc, and start in second semester. OP: that’s probably no help to you at all – but know that we’re wondering about it all too.
