Changes to Prerequisites over Time

Every quarter, the Registrar makes changes to course prerequisites. Many of these changes are benign, removing or adding alternative courses due to a course renumbering (such as MATH 20F to MATH 18). However, many other changes can have major consequences on students, particularly when new prerequisites are added to a course.

The following two reports highlight these changes for each course and when they were made.
