<p>Your credentials look great. As everyone else is saying, get a good SAT score to prove it.
Looking at your ECs, though, it appears as if you are involved, but only in academic pursuits and some tennis. There isn’t anything distinguishing yourself as a great student outside of school, and colleges are looking for well-rounded–not just in academics, but in music, art, design, or other fields. I’d say Harvard and Stanford would be toss-ups for you (they are for everyone), but you have good chances at Penn and Princeton.</p>
<p>Good luck!</p>
