Normally, courses are taken 'for credit' and are counted toward degree requirements and included in the calculation of the student’s cumulative grade point average (CGPA)
Sometimes students wish to take more courses than required and do not want to have the extra courses counted toward their degree. In such cases, a student may choose to “audit” a course, or take a course as “extra” to their degree.
Auditing a course
When a student audits a course, the course appears on their transcript and if all course requirements as required by the instructor are successfully completed by the student, 'AUD' is noted on the transcript.
Taking a course as "extra" to the degree
When a student takes a course as extra to their degree, the course will appear on the transcript and the grade will be noted but not counted in their CGPA, nor toward the degree. Should the student decide to pursue an additional degree at Waterloo or elsewhere, the 'extra course' will be eligible for transfer toward fulfillment of the additional degree.
It is the student's responsibility to ensure their student record is up to date, and to follow up with the course instructor, department, or institution, if any grade is missing from their record.
