Well, I do know that Cornell sometimes rejects really good applicants since those will probably not go there
Or some person misplaced your app. Or you forgot a part of your app. Or they think you are crazy for working on all those courses. Or etc.
Second, you don’t seem to have a focus in any major… and your EC’s aren’t really engineering stuff
Third, your school looks horrible. They might have just skipped over your school.
EC’s are kinda weak for SoCal
You’ll get into Berkeley!
MIT, Harvard, Stanford: mid-reach
Princeton, Yale: low-reach (lol, they like high-GPA + high SAT since it improves their ranking)
No idea about others 
(Hmm, If people at my school were allowed to take that many AP’s, then there would probably be about 20 people like that. But I guess they try to deflate the GPA/etc)
