how will quitting band junior year affect college acceptance?

My parents are presurring me into quitting band. I’ve done band 2 years in high school, I’m a current sophomore, but my parents don’t think that band is worth it anymore.

Before I go on: please don’t give me stuff like oh just do what you like, enjoy life, don’t worry about college, let your heart lead the way, etc. Etc. I’m here for purely reasons that pertain for colleges. I do appreciate advice like that, but no offense, it will have no impact on my decision.

Anyways, I’m planning to go to med school, so I really need to get working. Will colleges look negatively at me quitting and after two years? I’m not a leader and while my band is pretty great, (we just won state) apparently such accomplishments mean nothing if I’m not a leader. As an individual, I haven’t really done anything great, although I am most likely going to get an Outstanding in UIL state in my solo and ensemble. Again, this is probably nothing by med school standards.

Here’s the big cinch: next year we go to grand nationals and I am absolutely sure we will be a finalist. This competition is basically the best high school marching band competition and it’s global. Unfortunately, I don’t think I can be a leader next year either. How will colleges look at this grand nats? Will it be a huge boost on my application? Or be worth a negligible amount?

On the other hand: if I quit band, I will be taking 7 to 8 ap classes and boost my GPA significantly. My parents think quitting band is great because I can have more time to study and whatnot, but I think that having no ECs is a pretty big risk. I’m pretty sure my resume will be super boring if I don’t have something like band to embellish it. Please give me your feedback as soon as possible! Looking forward to it!
