<p>Personally, I am opposed to the specialization of high school students. If a high school student wants to participate in different types of EC’s and gain a broad base then I think that’s great. Still, it seems like the area which you are most interested in is computer science. Your free software plan for the summer seems fine, especially if you will be doing something technical there (and I assume you will be.)</p>
<p>When you say “olympics”, do you mean you were representing your country in computer science and physics? If so, these are very strong EC’s, even for an international student. If not, how far did you get in these competitions.</p>
<p>You are better off talking to an international student who got into MIT, especially from your own country, to find a typical profile of an admit. I don’t think any of the MIT students or alum that post on here are internationals. As you probably know, MIT limits the number of internationals they take due to federal funding rules, so their pool is significantly more competitive than Americans.</p>
