At OUAT, few seats are reserved as free seats and few are reserved as cost-sharing seats. For free seats, the fees are less. For cost-sharing seats, you will need to pay the additional cost for that seat. For cost-sharing fees, you will need to pay your readmission fees every year. So, students getting admission in cost-sharing fees, need to pay more fees compared to the ones with free seats. The admission to these seats is based entirely on merit.
