I was up last night carefully editing my common app essay just before the deadline to my first choice school. It was perfect - not a grammar or spelling mistake in sight, but I noticed one paragraph didn't quite end the way I wanted it to. I changed it round a little bit.
I submitted it last night. Tonight, I've noticed that when I changed it round, I didn't change one of the words to make it all make sense. I now have a sentence which reads:
"The school would urge its students to avoid loitering in the store or forming large groups and possible obstructing other customers."
This is the only mistake in the entire essay - believe me, I've triple-checked the completed, unchangeable draft which has now been uploaded and sent off on the Common Application. What do I do? Leave it? Send e-mails grovelling for forgiveness? Seriously, I'm not going to sleep until it's sorted. How badly will this hurt me?
