<p>How and Should I tell them extra awards I just earned after I have sent my application?</p>
<p>Of course you should tell them. Just send an e-mail. Of have your GC write a letter. That might be better; it's more official.</p>
<p>or you can always send your own letter</p>
<p>Woah now, sparky - this had better be a pretty kickass award (I'm thinking state champion of something at a minimum). People tend to overestimate the extent to which admissions people care about your extracurricular life, and sending them the spelling bee award you just clinched will only tick them off. The fact is that unless this award is major, it's probably not worth your time or theirs.</p>
