<p>Your academics look stellar; I don’t think you’ll have any issues there.
Your extracurriculars seem a bit simple, it looks basically like orchestra (I play cello too!). I don’t know that much about political science, but those activities look very good. The internship looks very nice too.
With your academics, I think you’ll be able to have a good chance at all of them. With the Ivies and Stanford though, I’ve heard that they can be a bit radical (admitting a student with a 1500 SAT and denying a 2300 SAT). Make sure you keep working on your ECs and leadership, a privilege us seniors don’t have at the moment…</p>
