Course selection HELP

I’ve taken the state standard minimum biology course for graduation.

Yes I think I misread the MIT website, I just checked again (they recommend 3 lab sciences but not advanced): Academic foundations | MIT Admissions

I understand that MIT specifically may not be a good fit for me. Overall though I’m wondering whether AP Bio will be more helpful in college admissions than dropping chorus is harmful. Also chorus isn’t weighted in our school so it is dragging down my GPA and class rank by a minor factor, too. But I do really love chorus.
