Submit Supplement In 10 Days?

<p>I sent my Common App last week, and just got an email that I need to send the CMU supplement in ten days? What's this time limit all about?</p>

<p>Call the school and get the answer from someone in the know.</p>

<p>I'm applying regular decision. The only reason the CMU app is already out is because I sent the Common App to my early decision school.</p>
