Declaring a Major

All majors in the College of Natural Sciences and Mathematics (CNSM) require that students begin as "pre-majors" and then meet precise major-specific criteria to officially declare the major. These criteria include meeting all major-specific degree requirements in the new major and demonstrating a progressively successful academic history that reflects potential success in the major.

All undergraduate students must have a declared major by the time they earn 60 units. Please see Declare a Major (Pre-Majors/Undeclared) - Enrollment Services for more information about this policy.

This applies equally to students who are:

• Undeclared or pre-major
• Requesting to change or add a major

Please see the Fall 2022 Major-Specific Requirements - CNSM from Enrollment Services to determine the major-specific requirements for your intended major.

How to Switch Your Major

If you are a declared student from another college and would like to switch to CNSM, please contact the assigned faculty advisor for your intended major: Find My Advisor. Students must have completed the Fall 2022 Major-Specific Requirements - CNSM for their intended major and meet the guidelines in the Timely Graduation Policy be eligible to switch to CNSM.

If you are a declared student in CNSM and would like to switch out to another college, please contact that college's advising center.

Things to Keep in Mind

• Submitting a request form does not guarantee your major change. Your form/record will reviewed by our Academic Team for approval. You should hear back from an advisor in about 2 business days regarding your decision and next steps.
• It is important to submit your request well in advance of registration or any other deadlines. CNSM Advising is not responsible for registration delays that may occur while requests are being reviewed and/or processed.
• Have a back up plan. For additional major and career exploration, visit the following:
