<p>Do something INCREDIBLE over the summer, I can’t tell you what, but make it something you’re passionite about. Also use it to prove you are social/cultured (learn an instrument in your spare time if you can). You can tell a lot about someones character by the way they respond in the comments and you appear to have a great one. You will go to a great school no matter what happens and are in an excellent position, but if you want to have a better shot at MIT/Princeton do something EC related that shows character.</p>
