At the place I went, they designed the curriculum around students that came in without it. But I guess testing out gives room for a gen-ed.
I dunno. The vibe in high school’s hardest math class and college’s easiest math class is kinda different. Might be worth doing both, haha. Easy A, too.
If you don’t take the AP class to test out of it, you’d have to take it first in college though.
I imagine many people strong enough in math to pursue sciences will go the AP route and test out of it, but not everybody takes the same path.
