<p>High chance? No.</p>
<p>As for the value of ECs, all top universities look for well-roundedness, so that argument is utterly invalid. Don’t get me wrong, I don’t mean to dissuade the OP from applying, but giving false hope to someone by rating their chances as being ‘high’ is a very cruel thing to do, as students every year realize when the decisions come out.
By virtue of being an international alone, your chances are never ‘high’ with top colleges. Just do your job to the best of your abilities, apply and leave the selection process to the adcoms.</p>
