<p>I’m not very familiar with the MIT application, but is it possible to list internships and summer activities as part of your 5 ECs? If so, that’s what I’d do–list the four activities I mentioned along with orchestra. If there’s a separate section that asks how you spent your summers, then do what you were thinking earlier. As far as chess club goes, I’m not sure I would list it unless you have a rating above 1500. If you have an impressive rating, mention it. MIT wants students who like to “get their hands dirty”, so you should pick activities that are consistent with that. As far as the “Seven Keys to Success” thing goes, list it in the awards section and if you write an essay about India, mention it there too.</p>
