I still stand by my earlier advice. Even if you can handle an extremely rigorous course load, you shouldn’t test the waters by adding three more AP’s the year you are writing your college applications. I suggest at least taking one AP class off - it won’t make or break your application but it will free up a lot of time. Like I said, APES is worthless unless you are going to study that in college. Some self-study the weekend before the test and still get a 5.
I’d quit band if I were you. Three clubs, AP homework, and college applications are enough. Band requires an extreme amount of work/time and it’s better spent improving your applications. Of course, it is your decision.
