A course that is non-repeatable is a course that cannot count more than once towards your graduation requirements. Most courses are not repeatable, and the catalog will confirm those classes that can be repeated. For example, if you take ENC 1101 more than once, only one the last attempt will be reflected on your degree audit. There are a small number of courses that are repeatable and thus, can count multiple times towards graduation. An example would be a music class that is a lesson.
