Agree with BlueMagic. That is the same situation that my DD found herself in this year. She was given the option of doing mostly college courses this year, and chose to take AP which are dual enrollment instead, simply because of the weighted GPA.
Evidently the local college thinks that there is nothing wrong with the AP coursework, though-- they were happy to give 2 quarters' worth of credit for the English and the math both.
For some AP courses/exams, there isn't a "college equivalent" course. AP Physics B is like that. The coverage is simply too much-- no ONE YEAR course at the college level covers all of what is in it. Yes, it's possible to cram an inch deep and a mile wide and get by on the exam, but truthfully, DD and her best friend both actually learned the material that well. She didn't bother taking the AP exam, but he easily rocked a 5.
So that's where I'm coming from when I say that actually, these classes CAN be a really great fit for an HG+ student, since they move at a pace and over SO much material that nobody else can keep up with it. But it's a pace that is probably as close to "ideal" as a kid like mine is going to get, short of college. So especially for young accelerants in particular, AP is a pretty sweet thing, I'd say-- less demand on still-developing EF (unlike a college course) and less damage long term if they make mistakes (more assignments, and let's face it, high school isn't college in terms of transcripts).
That vetting done by College Board may have hurt some very high quality AP coursework, but at the same time, I think it also means that ANY student who takes an AP class is at least assured of some minimal standard that passes muster. TEACHERS have to be 'certified' in the subject by College Board, as well. This is particularly important, IMO, in Math and Science.
