I think you shouldn’t worry.
You are spectacular and you have a lot going for you. But nobody can say - you’re a likely for Princeton. You just can’t - and while it’s great to have aspirations, you should just know you’re going to get an awesome opportunity somewhere.
What is about Princeton you like because perhaps there’s other similar schools in back up?
You certainly have accomplished all you can and that’s all you can do.
Until you’re accepted or not, you can’t worry - and if you’re not accepted and that’s likely, you can’t worry about why. You’ll never know - and frankly, you’re fantastic, so it’d be their loss.
What do you want in a school?
What is your cost situation - i.e. budget and if it’s not full pay, are you a a full pay family - meaning your parents may say $30K but schools would say you’d get no aid based on their finances.
Some can afford but don’t want to afford.
Also, what state are you from?
Let us know.
Thanks
