I messed up on my application.

<p>At this point, I really do want to go to this college but I don't think it's going to happen and it'd be a miracle if it did. Maybe I'm being over-dramatic because everything is in place but this one mistake.
I applied ED on 11/7 when the application was due 11/8 and I've just now noticed that I got one recommendation for a core teacher and one non-core teacher recommendation when this school requires two core teacher recommendations.
I'm 98% sure that the non-core recommendation is the better of the two because she knows me better and we understand each other. However, it doesn't meet the requirement.
Should I hastily get a paste-and-copy letter written from one of my core teachers, who have many students and don't really know me that well, call the college and have it sent in by Monday?
Or should I just leave it be, hope they don't notice and get started on my safety, match and other reach school applications?
I'm purposely not saying the name of the school because I just don't want to. But it's a pretty awesome liberal arts college with about a 23% acceptance rate.</p>

<p>There is no need to panic (yet). Most colleges accept teacher recs and test scores a little after the deadline. Just fulfill the requirement, even if the rec is not going to be amazing (but you really have never had a teacher for a core class that knows you well?). Give yourself a fair shot. It would be a shame for you to get denied just because you did not give the school what they asked for. I would get the other rec and call the school informing them that it is on the way.</p>
