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.
I did. Most of my honors track classmates did. And we also had hybrid courses, ie AP Humanities, that had the full AP English and AP History in them. The exception was the Physics II and Chem II classes that just had a handful of us in them.
For serious STEM students in HS, nowadays, they should also be focusing on the AMC 8/10 tests as well as other competitions.
