<p>I had given my teacher the recommendation form for my NYU application to mail, but I found out last week he forgot to mail it. So last Thursday I had the documents overnighted to NYU. How detrimental will this be to my admission? Everything else was sent about on time...</p>
<p>Colleges won't hold you responsible if your teacher rec is mailed late; that's primarily the teacher's responsibility, not yours, and besides, they probably haven't finished sifting through the materials they've received.</p>
