Co-requisite Course Required

Definition of Co-requisite: Two courses that you must be registered for in the same term. This is common for science classes and labs.

  • You must register for both the main course and the co-requisite course at the same time during course registration. 
  • Sample error message: BIOL-111-01 requires concurrent registration in BIOL-113.
  • There are times when it is fine to override this course requirement (for example, you may decide to take BIOL 220 without the co-requisite BIOL 221 lab). Exceptions may be made by using the paper Registration Override form and obtaining consent from the appropriate department head.  Turn the form into the University Registrar's office within normal registration deadlines.
