USC is as good of a dream school as any. Even if you’re overqualified, you might have a shot at being in the top 20% who receive a merit scholarship. Going to USC with even a half-tuition scholarship is one of the best choices of college available out there. Be careful with complacency though. You’re from a public school competing with 50% of applicants who are from prep schools with insane grade deflation and competition. 29% of accepted applicants have a perfect 4.0 UW. Your ACT score is only in the middle 50% of those accepted.
That said, your ECs will push you over the edge, I’m sure. It’s just that the rest of the posters here don’t really have a good picture of that. USC is definitely the most selective college on that list, including Mich Ross.
