How do I know what GE paperwork to fill out for my upper division GE course?

Any course number between 300-499 is considered upper division.  In 2019, a new GE program was implemented that had significant changes to upper division GE classifications.  Rather than overlapping with other GE subareas, all upper division GE courses now reside in their own categories: UD 3, UD 4, or UD 5.  You should choose the appropriate category for your upper division course from these three options.
