Prerequisite and Test Score error – The class you have checked for registration has a prerequisite requirement which must be approved by Counseling and Student Support Programs. Please contact Counseling and Student Support Programs at (530) 938-5353.

Repeat exceeds 0 for satisfactory grade count – Most classes at COS may only be taken one time. Some classes are repeatable; these are noted in the COS Catalog. This repeat message means that you have taken the class the maximum number of times allowed. If you feel this is an error, please contact Counseling and Student Support Programs at (530) 938-5353.

Time conflict with CRN XXXX – This means the new class that you have requested to add is conflicting (in whole or in part) with at least one of the classes already on your schedule. Check the days and times of your classes for the conflict. At this time, you will only be able to register for one of the conflicting classes online. If there is an overlap, you must complete an Overlapping Classes Permit that must be signed by both instructors and the appropriate Area Dean then submitted to the Admissions and Records Office to register for the overlapping class. The Overlapping Classes Permit and Add/Drop forms are available in the Admissions and Records - Forms area of the COS website.

You may NOT add or drop classes due to holds on your record – You may view your holds by selecting View Holds from the Student Records menu. The typical holds are for:

  • Dismissal – If you are on Academic or Progress Dismissal, you will need to meet with a counselor.
