Time-tickets are assigned with priority to students scheduled to graduate for the upcoming registration term and then to continuing students according to the total credit hours earned. Therefore, time ticket assignments cannot be changed. Once a student is allowed access, the student can adjust his or her schedule on a first-come, first-served basis during the remaining registration period. Many classes fill up quickly. It is to the student’s advantage to attempt to register as soon as he or she is allowed access to the registration system.
