Wayne State University: Re-enroll, we'll forgive your debt

The second paragraph of the article says they will "forgive up to $1,500 of debt for students to re-enroll and finish their degrees". There is no mention in the article of how much it costs to attend this school.

A quick look at the Wayne State University "Tuition Fee Chart" suggests that in-state undergraduates pay approximately $400 per credit hour (less for lower division courses, more for upper division), not including other fees.

Their debt forgiveness program appears to be worth about 4 credit hours. Anybody know how far 4 credit hours will get you?
