You are quite an impressive young lady. Make sure your essays show who you truly are as a person, what you are passionate about, etc. Not so much a writing contest, but an inner glimpse.
My advice would be to keep working hard, to focus on extra-curriculars that are more community-based (that you are passionate about), and to not focus on just the Ivies.
There are so many wonderful colleges available to someone like you. I went down this path with my son two years ago, and he was almost certain he wanted to go to an Ivy as well (similar stats, 4.0 unweighted, 5.0 weighted, with near perfect SAT II’s). We went on a lot of college visits. And guess what…
He ended up applying Early Decision to Pomona College after a fantastic visit, and he absolutely loves it. You can succeed at any school you attend, and you can be happy wherever you end up. Have seen so many kids hyper-focused on HYPMS, and they were crushed (and kind of lost) when they were not admitted.
Look hard at other options and be open to all your possible choices! Best wishes!!
