@OrchidBloom: Thanks! I attribute lower math scores to being naturally better at history/english, but despite that having a real passion for STEM.
Dayummm academically you destroy me. Lol your really smart and since you have legacies and good ecs your chances are prolly pretty high. You will definitely get into one of those schools you mentioned. I wouldn’t doubt it due to your high gpa, sat and good ecs. Only school that may reject you is Stanford and that’s cuz their really selective.
@Kumar452, Thanks for the reply! 
You’re ECs and awards (especially science research) definitely make up for your GPA, which isn’t much of a problem in the first place if you go to a prestigious prep school. I would be very surprised if you aren’t accepted to at least 2 or 3 of your top choices.
