Ummmm....it goes to first semster's tuition at most schools. As far as financial aid...deposits have nothing to do with it.
YOu get reimbersed in the sense that say you paid a $100 deposit, well your first semester's refund check would be $100 more than what you woudl expect...then again it's all cancelled out by any shots and other fees you ahve to pay they might get you with.
