How many science and engineering majors are likely to have taken AP humanities courses? Sure, I suppose there are a few, but I think that people mostly take AP courses in their area of focus. I don't remember anybody, even the most gung-ho students, taking all of the available AP courses when I was in school -- and there weren't as many then as they offer today.
In my kids' high school, about 500 of the 1000 students in each grade level were signed up for at least AP English, and a majority of those 500 were also signed up for AP Biology, AP History and AP Calculus. As long as a student could keep a C average, they were allowed in the class.
AP wasn't even invented when I was in school.
