College grad here, not one AP.
Two kids in college, one did get credit for AP Art History, and probably took 4-5 other AP courses but didn’t score high enough to get college credit. That was fine, she didn’t need it and has to take art history courses anyway as it’s her major so the credits didn’t help. She also dropped her French course, which would have been 2 years of the same language, as it was online. She’d already been accepted to college, and only thing the college said was that she’d have to take it in college. Art History major, she needs two full years of college language, so she started over and is fine with having to take it from the beginning.
Other daughter took 4 or so AP’s, didn’t get any credit but was happy with the strength of the courses. She got A’s in chemistry and calc her freshman year in college. She did take Spanish through AP (so 4 years) and cannot speak 4 words of Spanish. Not required for her major (civil engineering).
I wouldn’t worry about it. He should take what he likes (or required).
