In some cases, you’re expected to complete a course or get an appropriate score on a placement test before being allowed to enroll in a higher-level course. Prerequisites are usually listed as a class note in the schedule of classes. For example, “P: ENG-W 131” would indicate that you must complete ENG-W 131 or its equivalent before you can enroll in the course in question.
What happens if you try to enroll in a course with a prerequisite
If you’ve met the prerequisite requirement, you’ll be able to enroll in the course as normal.
If you’re eligible due to your current enrollment in the prerequisite, you’ll be able to enroll in the course. The department offering the course will verify after the current term that you passed the prerequisite.
If you haven’t met the prerequisite requirement and aren’t currently enrolled in the prerequisite, you’ll get an error message saying you’re not eligible to enroll in the course. Contact your academic advisor for more information.
Prerequisite screening issues
There are some prerequisites that the registration system doesn’t screen for. Departments reserve the right to review class rosters after registration to make sure all students are eligible. If you turn out to not be eligible for a course you’ve enrolled in, you may be asked to drop the course, or you may be administratively withdrawn. This is also true for any course with the note “Consent/Permission of Instructor Required.”
