Before Registering for Courses

  • Before each registration period, you will see an "appointment time" in UDSIS that indicates the earliest time that you can begin to enroll in classes. You can find this under the "Courses & Enrollment" tile (example to the right) under the "Enrollment Dates" menu item.
  • The Registrar's Office assigns the appointment times based on the number of earned credit hours you earned (e.g., seniors will have priority registration over sophomores) and CANNOT be changed.
  • Use Courses Search to see if there are open seats in the classes you want. If a class is open, and you have met the prerequisites, then you can enroll yourself into the course.
  • If a course you want has a prerequisite in which you are currently enrolled at UD, then the system will let you register for the course. For example, you want to take PSYC207 but you are currently enrolled in PSYC100. The system recognizes the PSYC100 as being in progress and will allow you to register for PSYC207. However, if after grades are posted, you do not have a C- or better in PSYC100 (all major courses have a minimum grade of C-), then the Registrar's Office will drop you from PSYC207.
