The course materials fee pays for eBooks, 3rd party websites, media and other copyrighted materials included in the course. It is not a tuition fee.
Because it is similar to buying a textbook, most students must pay for the course materials fee including senior auditors, and students with a scholarship or tuition fee waiver.
If you have a scholarship that does cover the purchase of textbooks / course materials, then you reach out to the Financial Aid Awards office to see if this fee will be covered for you.
