How to update schools on new ECs?

<p>How do you update schools that you applied to RD with things like:</p>

<p>won big science fair award or got a new job etc..</p>

<p>i know not to update with like did 10 hours of community service..but how do you update them with something big?</p>

<p>well, I would send a letter to undergraduate admissions, with your common app id # plus your name and address and school and explain what you won/did.</p>
