<p>I'm applying online through the commonapp and there seems to be a problem. After applying ED for Penn and getting rejected, it seems I can't modify/edit my common application, but I can still submit my supplement. </p>
<p>Should I submit my supplement online, and the common application + teacher recs + GC recs via paper? I think that's the only way to go, seeing as I want to make changes to my commonapp.</p>
<p>Most schools do not allow you to edit previously submitted materials if you are deferred. You may send updates via mail if you think it is necessary. Be sure to list your name and birthdate on any correspondence and call the admissions office after a week or two to make sure they’re received any supplemental material.</p>
<p>Keep in mind that added material - unless truly extraordinary - probably wont make a difference in whether or not you are accepted regular decision.</p>
