Each requirement within the Advising system is identified by an Advising Requirement Code (ARC) as it is defined in this table. The calculations that take place within Advising to determine a student's progress are based on the ARCs. Courses that are completed by a student are entered into the Advising system through the requirement codes that have been associated with the courses in the Registration Catalog Master table and transported into the Student Course History table. A priority code can also be associated with the requirement code to control the priority that each requirement receives in comparison with other requirements in competing for a course to satisfy itself. These ARCs are linked together in the Institutional Requirements Areas table to define graduation requirements.
