See #6 under F in the Other Provisions section of the Grading and Transcripts policy
Repeating a course at Morris
The University of Minnesota registration system enforces the one repeat rule* as defined in the Grading and Transcripts policy. Students may repeat a course one time. In addition, if space is not available in the class, a Morris student who earned a grade of C or higher or an S in a particular course may be denied enrollment in that course. The University registration system will not allow students to register for a course they have already taken twice. Attempting to register for a course for a third time will result in an error message in the registration system.
*Repeat rules do not apply if the repeated course carries the same course designator and number but the content differs each term, or if the course is designated “repetitions allowed.”
Petitioning for exemption for the one repeat rule
Students who want to take a course for a third time should consult their academic advisers to explore other options.
