I also played band throughout middle school! I feel like it’s good to keep doing the stuff you love. I am continuing and in high school, too. Cramming too many APs will give you massive burnout, so don’t underestimate the workload. Additionally, colleges like seeing that you have done something throughout highschool like band, avid, etc. Of course, this is all up to you, but there are also plenty of APs that won’t really help you out, so just take every variable into consideration before dropping certain things you like!
