A student who is a non-major must satisfy the control requirement by obtaining a permit or authorization for the section. Registration controls work in conjunction with the priority rule established for the course. The scheduler looks first at the registration control and eliminates all requests of those who are not eligible. The scheduler then ranks those who are eligible according to the priority rule of the course. It then looks at students' registration sequence numbers and the assigned random numbers for final ranking of course requests.
Quotas restrict seats in a course section to defined types of students.
Quotas can limit seats or reserve some or all of the seats in a course section. The student's authorization overrides the quota, if there is one, but the student's request is subject to the priority scheduling rule established for the section. A course requires department permission because it has prerequisites. The department issues authorizations to all eligible students, who then compete, through the scheduler, for seats in the course. The authorizations will not override the maximum enrollment on the course section.
