It is advisable to register early because several classes close. The instructor's permission is required to enter closed classes and can only be entered the first day of the semester.
A waiting list option is available on all closed classes. Students are placed on a waiting list in the order in which they tried to enroll in a specific class. Students must attend the class on the first day and get the instructor's signature on an add slip or registration form. The student then would submit that signed form to the Admissions Office at which time he/she would be officially enrolled in the class and pay the appropriate fees. If students do not attend that class on the first day, it is assumed they have decided they no longer want to be enrolled in it.
