For many classes that are short session (E.g. Six or Nine week sessions) it is possible to enroll in sequential classes consecutive sessions during the same term. An example of these classes would be Math 80a & Math 80b, or Cos 50a, Cos 50b, and Cos 50c.

The online enrollment system does not recognize prerequisite as being met during the same semester. If an attempt is made to enroll remotely in this situation the student will recieve an ERROR.   

In order to enroll in these classes you must enroll in person in the Admissions, Records, and Services Office.
