If you really want to go, apply and re-class. As others have said, it’s an easier entry point, and it’s very risky to jump into those meat grinders in 11th grade, a critical year from a college admissions standpoint. Especially at PA, where 11th is the hardest year of all.
But that said, the reason to go these places isn’t to get into a great college. It actually makes it harder in some respects. The reason to go is to be prepared to do great wherever you go to college, which sets you up well for grad school or whatever you want to do after. Three years of that experience beats two.
