You must be admitted to the university before you can register for classes. If you haven't yet applied, apply online or contact USD's Office of Admissions for more information.
After you have been admitted, you will receive information on registration prior to the start of your first semester.
Typically, you will select a day or event for your on-campus registration (Coyote Registration for students entering in the spring semester and Fast Track Registration or Overnight Registration for students entering in the fall semester). On your registration date, you will meet with your advisor and register for your classes.
