The cost per credit hour at the University of North Carolina Wilmington (UNCW) varies depending on your residency status (in-state or out-of-state) and whether you are an undergraduate or graduate student. There's no single, readily available "per credit hour" number that applies to everyone.
To find the most up-to-date and accurate cost, you should check the UNCW's official website, specifically their tuition and fees page. This page will usually break down costs by student type and residency.
