Hello there.
Honestly, I’m not sure what your chances are (I can’t do chances. I’m in 8th grade applying to the same schools as you)
However, I advise that you send a video in for your piano playing.
The thing that puts you at a disadvantage is the fact that, like me, you are an ORM (Overrepresented Minority) and also that many are applying from your school.
One question: Are you applying for financial aid? If so, then that puts you at further disadvantage.
Also, I used to love kpop too. Anyways, you should write about something you’re passionate about. The issue is… based on your interests/passions, I don’t know if these schools are right for you. Exeter and Andover are academically rigorous. I can see why you would want to go to Choate (arts concentration), but it’s still very academic. The most I can say is to pour your heart and soul in these essays.
Not only that, but you have to think about why the school would want you? Based on your ECs, you can join their squash team, and also you have musical talent. You don’t need to start some “TED Talk” or start a fundraiser to get accepted, but you do need to show that you have done volunteer work before.
But I believe you have a chance of getting in! I would say to add more schools but with the deadline so near, that’s not an option lol. I really don’t mean to discourage you and I hope this advice helps.
P.S. Why am I doing this when I should be in class.
