College of Professional & International Education
If you are interested in taking a course in the College of Natural Science and Math, and the course has prerequisites, you may not be able to enroll yourself through self-service registration. The instructor will need to verify that you meet the prerequisite requirements and give you permission to enroll in the course.

The instructor will either assign you a permit or permission number, allowing you to register through MyCSULB Self-Service Registration if you have access; or you will need to complete the May Intersession Online Registration Form.

Please contact the instructor for approval before submitting your registration form.

You can find prerequisite requirements in the university catalog at​

If the course is full, you will need to wait until the first day of class to contact the instructor to obtain approval before submitting a May Intersession Online Registration Form. Please do not submit your registration form until you've received the instructor's approval. The approval must be included with your registration form.
