I would really like to go to UC Berkeley or Northwestern University. Am I on the right track or should I get more involved?

Well, you don’t have a 2400, 8 published research papers, or an internship with Bill Gates, so you might as well not apply. /sarcasm

You’re doing fine, and you’re on the right track to get in to those schools as a senior. In fact, you’re pretty competitive as a sophomore.

Holy crap, that’s impressive. You’ve got a really good chance, in my opinion. And three APs as a sophomore. Wow. We’re not even allowed to do that at my school.
