Curious about how many AP classes seem to be the norm now. I asked someone, who entered Princeton about 8 years ago how many AP classes she had taken, her response: "all of them". DD is striving to take AP Chinese next year (10th grade) and AP computer science (since she has been in computer club for several years and AP CS is expected to be easy). Then the expected: English, Calc, Bio, Chem and Physics. She is taking AP Chinese through CTY, because it is the only way she can, and then doing the same with Spanish in 12th grade, since her school only offers 3 years of Spanish and not AP. When I was in school in Canada, we had grade 13. That was AP. Grade 13 physics was basically first year physics at university. Not exactly. And you did not get any college credit, it was to show you could do the work or something.
Since we talk about acceleration here a lot. You can do acceleration through these online programs. Have people applied for scholarships? Are there scholarships for high schoolers to move ahead? Maybe that should be a thing.
