Declaring a Pre-Major

If you are a pre-major in CNSM and would like to switch out to another college, please contact that college's advising center; see Academic Advising at CSULB for college advising center contact information.

At the time of admission to the university, each undergraduate student is assigned to a pre-major or major or is designated as an undeclared major. All undergraduate students must have a declared major by the time they earn 60 units.

How to Switch Your Pre-Major

First-time freshmen (FTF) in their 1st, 2nd, or 3rd semester since admission admitted as undeclared (UNDCL) or non-CNSM pre-major admitted to a different college may switch their pre-major to one of the pre-majors offered in the College of Natural Sciences and Mathematics (CNSM) if they demonstrate good academic progress towards meeting mandatory declaration requirements for their intended major. The typical expectations include CSULB GPA of 2.5 or higher and the following.

1. Students in their 1st semester at CSULB: enrollment or credit in MATH 119A or 122, and CHEM 111A (if CHEM required by the major).
2. Students in their 2nd semester at CSULB: credit in MATH 119A or 122, and credit in CHEM 111A (if CHEM required by the major); or enrollment MATH 119A or 122 and a "B" or better in pre-calculus course(s), and enrollment in CHEM 111A and "B" or better in CHEM 102 (if CHEM required by the major).
3. Students in their 3rd semester at CSULB: credit in MATH 119A or higher, enrollment in MATH 123, and credit in CHEM 111A or higher and enrollment in CHEM 111B (if CHEM required by the major).
4. Students in their 4th or higher semester at CSULB: these students are not eligible to declare a pre-major, and instead must complete mandatory declaration requirement and declare a major.
