Corequisite Error in Banner


This article details how to handle co-requisite errors you may receive when enrolling in classes.



The error is caused by a mismatch of CRN numbers for courses. 

  • E.g. CHEM 124 requires enrollment in CHEM 125 during the same semester.
  • You receive an error message simply because there is a specific CHEM 125 course you must be enrolled in simultaneously to CHEM 124.
    • Look under the Corequisites section in the Class Details pop-up that is accessed by selecting the title of the course in the listings in Banner.

To fix the issue:

  1. Check the Corequisites section in the class details.
  2. Note the CRN of the needed corequisite course.
  3. Enroll in the course.
  4. Once both courses are listed in the Summary section, you should no longer get the corequisite error.
