A prerequisite is a course that must be completed with a grade of “C” or better before taking a higher level course. For example, to take a 2000 level (sophomore level) English course, you might have to take a 1000 level (freshman level) English course first. Prerequisite courses teach the skills needed to be successful in the next level course.

A "recommended" prerequisite is one that is strongly encouraged to prepare a student for success in a higher level course. But it is not required.

A student actively taking a prerequisite course can register for the next more advanced course in the next term. But if the student receives a final grade of "D," "F,” "NC," "W,” or "I" in the prerequisite course, they will be dropped from the more advanced course.


A corequisite is a course that is either recommended or required to be taken at the same time as another course.  For example, a biology course might require a biology lab course be taken during the same term. If a student wants to drop a course that has a required corequisite, the corequisite must be dropped also.

All required prerequisites and corequisites are enforced when a student attempts to register. All prerequisites and corequisites are listed in the course descriptions that can be found in the CNM Catalog.

Five ways to meet a course prerequisite requirement

  • Enroll in the prerequisite course at CNM. Complete it with a passing grade of "C" or higher.
  • If you have completed an equal level course at another regionally accredited college with a “C” or higher, it might meet the prerequisite requirement.
  • Reaching certain scores on the Accuplacer placement exam could qualify you to bypass a prerequisite.
  • ACT or SAT scores that are not more than five years old could qualify you to bypass a prerequisite.
  • Request special clearance.
