Environmental Sciences, B.S. requirements

The 2026-27 catalog, with the courses that satisfy each requirement and which ones are offered this term.

Why the catalog year matters

Your catalog year is the year you started at SDSU, and it decides which rules apply to your degree, not the current semester's course list. Always check the requirements for your own catalog year - see every catalog year on file for this program.
