I agree with Mr. Lynch. I only want to add that tuition is dischargeable. If you did not finance this with a student loan, and you are otherwise eligible, you could eliminate the debt by filing a bankruptcy petition.

The fact that you never set foot on their campus is irrelevant. Their offer of admittance, presumably last Spring, was met by an acceptance of their offer of admittance and, undoubtedly, the terms of their offer. That sounds like a contract, one that you breached. In every contract breach, the non-breaching party has a duty to mitigate their damages. There is much detail left out of your question but your waiting until after the add/drop deadline suggests that you led the college to believe you were coming until the last minute. The problem that creates for you is that they will argue (successfully, I believe) that, by so doing, you eliminated their opportunity to mitigate the damages caused by your breach - like admitting some other applicant off their wait list to take your place. Others may disagree with this analysis but you have a problem that can affect your credit if you don't deal with it, in my judgment. I would contact them and see how much they would take in compromise. If you have a hardship excuse, that might help you, but you need to address it.
