"You would have gotten into some Ivies for sure. I was kinda like you back in HS. If you won national medals for Decathlon you woulda gotten into HYP definitely.
sadly, competing against the schools that regularly took nationals didn't get my school beyond regionals (Curse you varsity team!)
I was good all around, but i was nearly perfect when it came to history: which is my major now.
I'll admit that it's one of my regrets that i never applied to any elite private schools. there were many factors influencing my decision at the time: Money (i'm from a poor family), race (didn't want people to think i got into a school because of that (Berkeley doesn't use affirmative action)), anti-elitism (i still harbor this), and pure intimidation.
to add to the thread: one of my professors put it this way- "graduating from Columbia (grad school), can get you a job at another elite school like Stanford, while graduating from North Dakota (grad), could get you a job at North Dakota. yet if you do great research and get the bancroft prize then your next job might be at yale.... but then the publications read for the prizes don't usually include North Dakota."
