While I suspect you have a chance everywhere, I do think Harvard and other T5 schools are really a long shot. You indicated top 5-6% of your class. Harvard, Yale, etc… Absent a major hook or recruited athlete, they really only admit top 1-2% of a given HS class.
I do think you have a very good shot at many of the T10-T20 schools. Georgetown, Northwestern, etc – I think you’d have a + chance at those.
Mind you – They are ALL “reaches.” But I suspect you’d be a very very competitive candidate at a school like Georgetown.
Your achievements are fantastic. But a school like Harvard has the luxury of looking for virtual academic perfection.
