Did you receive a P grade in a major requirement course in Spring 2020? Please note that while your P grade is accepted by the department, it will not show as completed in your Degree Progress Report (DPR) automatically. Your DPR does not inform the enrollment system of your prerequisites, so there is no consequence to not having your P grade reflected in your DPR.
