Teacher Recommendations

<p>So...
my Chemistry teacher is writing one of my recommendation letters but she's mailing it instead of doing it on the Common App.</p>

<p>I asked her today if she had sent it, but she said that she was working on it and gave me no date about when she will send it. Since the deadline is in a week, I'm getting a little anxious.</p>

<p>I'm applying ED to UPenn, and wondering if one of my teacher recs come late (past the deadline), will my application be penalized?</p>

<p>I really hope not...</p>

<p>Thank you to all that reply! =D</p>
