A prerequisite is a paper that must be passed before taking another paper or course. Some papers have more than one prerequisite.
If you have not completed a prerequisite for a certain paper you will not normally be permitted to enrol in that paper.
For example, it is not normally possible to enrol in ZOOL 222 without having passed CELS 191 and either:
- BIOL 112, or
- HUBS 191 or HUBS 192 with at least a B pass
Corequisites are papers that must be taken concurrently with another paper (unless it has already been passed). For example, students are expected to take both EDUC240 and EDPR240 at the same time.
To check if a paper you want to add has a corequisite or prerequisite, see the paper details on the Subjects and papers page:
