incentivized kids to take supereasy classes in 12th grade.[/quote]
It really depends on the school. I have a student right now who wanted to drop my AP class. He asked Cal Poly SLO if he could (his first choice school). They told him his acceptance was based on the senior class schedule he told them he was planning to take and they wouldn’t guarantee admittance if he changed it.
But it does happen a lot. My AP class is only a semester. Last semester I had about 55 AP kids total. This semester I was supposed to have the same but only have 30 because so many dropped it.
