Since you go to an elite private high school.. your chances with a 3.3 UW GPA (especially a perfect score on what actually matters to colleges,
Your chances at top colleges are higher than someone with your stats at a public school.
If there is grade deflation.. I would say that you should definitely get into schools at the Vandy/Emory/NotreDame level.
Ivies/Stanford/Duke/MIT will be a little harder.. my guess though is that on that level (due to high SAT scores), Cornell, Dartmouth, and Duke are the schools you'd most likely get into out of that group..
Good luck next year!
