What is a corequisite?

A corequisite is a course that must be taken at the same time as another course. This means that a student cannot enroll in the required course without also enrolling in the corequisite course. The purpose of corequisites is to provide students with the necessary background knowledge or skills needed to be successful in the required course. Corequisites are outlined in a university or college's course catalog and are often listed together with the required course in the course schedule. It is important for students to pay attention to corequisites when planning their course schedules to ensure they meet all necessary requirements for each class.
