the drexel acceptance letters says: "To reserve your place in the first year class entering in August 2012, we ask that you submit a $100 pre-registration deposit in the form of a cashier's check, certified check or money order in the enclosed envelope. Please make the check payable to 'Drexel University College of Medicine.' The fee will be applied to your tuition upon matriculation and is no longer refundable."
Does this mean no longer refundable (a) upon matriculation or (b) if you don't matriculate?
