<p>Literally 20 seconds after I submitted my apps..I noticed that I left out the word "an" before the word "environment" in the last sentence of my whypenn essay...I proofread it like 4000 times and had it proof read by other people..although i changed the last sentence right before i submitted so I must've forgot to add the an and the last person who proofread it must have not have noticed either...</p>
<p>should i contact penn and change this? or is one "an" not going to make a difference? it's the last sentence of my essay too =/</p>
