Use the course catalogue to find the course for which your name should be listed and contact the course supervisor or the current teacher directly to add you to the course, or contact the head of the supervising department to modify the course.
According to the CBA, the course content is the responsibility of the course supervisor, so the primary responsibility for teacher adjustments in the course should be carried out by the course supervisor; if the supervisor is not listed or cannot be contacted, please follow the information above and contact the head of the department (studio, department).
