No Confirmation letter-should i worry?

i submitted my UC application online on Nov 21 and i have not recieved anything in my email or mailbox. is this wierd?

<p>I have found with a couple of schools their confirmation has come well after completion of the application. In fact, i just received a confirmation today for an application I submitted one and a half months ago. Calling or e-mailing once wouldn't be a bad idea, it shows your interest anyway!
