No graduate courses are retakeable. That means you cannot take a course a second time and erase from your graduate record the grade from the first taking of the course. However, there are graduate courses that are repeatable. That means you can take a course a second time, and your grades from each taking of the course will be part of your graduate record. A few courses are designated as repeatable in the Registrar's course offerings listing, such as CHE 6000 (Seminar), CHE 6950 (Thesis), CHE 8950 (Dissertation), and a few others. Most CHE graduate courses are listed as non-repeatable, but those courses can be repeatable--by permission of the department graduate chair. For more information, contact Tom Riggs.
