I don't accept his premise.
He is worried about non-science majors missing out on introductory level science courses, and science and engineering students missing out on introductory level humanities courses. How many non-science majors are likely to have taken AP Science courses? 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.
