Spring 2021 classes eligible for Freshman Full Year Registration are designated by the Course Attribute, “FRFY Freshman full year reg,” in the CCS Basic Data tab.
Classes with the attribute are open for registration, but only to students with the “FRFY Freshman Full Yr Registration” Student Group on their record.
If you discover your department missed applying the FRFY attribute to a class, the CCS scheduler should add the attribute in CCS. A daily query identifies those with a newly added FRFY attribute, and the requisite stopping them from registering for the class is removed to allow freshmen to register.
