Waitlist provides many advantages to students, instructors, and administrators. The biggest advantage to students is that they are notified when a seat becomes available on a first-come, first-served basis throughout the registration cycle, until the 5th day of the semester.
Waitlist is advantageous to instructors and students by eliminating add cards for full classes until the fourth day of the semester. Waitlist is helpful to administrators by allowing them to track the demand for certain courses and better manage curriculum offerings.
