Course prerequisites
In order to enroll in some courses, you must either complete (prereq) or concurrently register (coreq) for certain other courses, possess particular qualifications or have a certain class standing. These requirements are known as prerequisites or corequisites. If you attempt to register for courses where you don’t meet the prerequisites, you may need to obtain a class permission number from the instructor or department offering the class and enter into MyU: Academics (see step-by-step instructions).
To see the prerequisites, you must select the class number or the course section information and view the details in the course description.
When courses that must be taken in sequence are prerequisites, only the last course of the sequence is listed. When no course subject precedes the course number listed as a prerequisite (e.g., "prereq 3221"), that course is in the same subject as the course being offered. Likewise, a prerequisite reading "6 cr" means 6 credits in courses offered by the same department. A comma always means "and."
Transfer courses that substitute for a prerequisite course are not recognized as a prerequisite in the registration system. Contact your course instructor for a permission number.
In some instances, instructors will determine that you have the appropriate academic background to enroll in a course even though the prerequisite has not been completed. Instructors may waive prerequisites at their discretion. You will require a permission number from the instructor to register for the course.
Occasionally, a class will be limited to students of a particular class standing. Your class standing is determined by your total number of completed credits.
| Class standing | Completed semester credits |
| Senior | 90 or more credits |
| Junior | 60.000 - 89.999 credits |
| Sophmore | 30.000 - 59.999 credits |
| Freshman | Less than 30 credits |
