<p>It seems like your brother could give you the best advice. But since you asked, your ECs look good. Of course, when you list them on the application you want to describe each EC with a few key words or a short sentence at most.</p>
<p>The research is your main distinguishing factor. If you could get something published, that would be impressive. Otherwise you should definitely find an interesting way to describe it in one of the essays.</p>
<p>I have a different take on some things than have been previously stated. Please check this stuff out for yourself with the admissions office. I don’t think you will gain anything by submitting raw research data as supplementary material. The admissions officer will not understand it and will be bored by it.</p>
<p>I don’t think you will be able to submit a violin tape unless you are applying for some type of major where you would be playing the violin. The standard admissions officer would not be qualified to evaluate your violin playing ability and would not listen to the tape. You should check on this before sending a tape.</p>
<p>Here is another thing you should check on. It was my understanding that the testing agency for SAT II scores will send all of them to the colleges you list. They will not allow you to pick and choose scores to send. I am not 100% certain of that, but it is the testing agency you have to ask as Stanford does not have anything to do with the sending of the scores.</p>
<p>Finally, I want to make it clear that I think you are an excellent candidate for Stanford and that you should feel optimistic about your chances of being accepted. I would encourage you to apply EA if you have everything together by the deadline.</p>
