I had a student in one of my classes explain this to me at one point. Every semester when it came time to pay his tuition bill, he would simply max out all of his credit cards paying the bill. The university system would let you pay as much as you wanted, and if you had a balance a week after tuition was due they would send you a check for the balance. While it was primarily in place for students receiving scholarship money, he used it to rack up huge rewards on his credit card. By the time he was a junior (when I had met him) it had gotten him good enough credit he had over a $15,000 limit, so 3 times a year he would pay that to the school, they would pull out their $15 credit card fee, and then deposit it straight into bank account, which he would use to pay off the credit card.
