An official withdrawal is when a student actually drops or withdraws from a course through MyUMGC, a military portal, or through an academic advisor prior to the published drop/withdraw deadlines for the applicable term. An unofficial withdrawal is when a student never attends/participates or stops attending/participating in a course. For unofficial withdraws, UMGC will use the last date of participation to determine if the service member completed at least 60 percent of the course.
