<p>Many people underestimate the importance of good ECs. An anecdotal piece of evidence that may or may not apply to your situation is one of my friends: 2350/3.9 with ECs that are similar to yours. He was rejected from all the ivies, UCLA, and UCB. He is now choosing from UIUC and UCSD.</p>
<p>I am not saying this is what will happen to you, but if you want to be sure that you will get into one of your better schools, you need a more well-rounded application.</p>
