Lets assume that Winthrop has an overall cost of $20000 in state. That is tuition, room and board. Lets assume they have 7.5 scholarships, so that is $150,000. Now lets assume they have 6-9 out of state waivers which is the norm for a number of South Carolina schools.
That means that a kid from Kentucky will use on of the 6-9 waivers along with 20,0000 from the soccer money she will have a full ride.
That is how out of state waivers work in the state of South Carolina
