How many AP classes/honors should I take for a competitive school?

Based on what you said, @juliaa99 , here’s what I’d suggest:
Honors English, Honors Algebra 2 (to get a strong foundation in both, as you’ll need that for upper level classes)
Regular Global, AP Bio (unless you’re allowed to take Honors physics or AP Physics 1 - do check with your GC), and French Honors, plus another class of your choice.
