The summer tuition rate is discounted from the fall/spring per-credit rate to encourage students to take advantage of summer course options. As a result, there is very limited aid made up of federal loans and Pell Grant for eligible recipients. There is no merit-based aid during the summer.
Summer tuition rates can be found here.
The cost for summer tuition is due by August 1st for students returning in the fall. Students who are taking summer classes as their final term will have 30 days from the day they're billed to pay.
