Bachelor of Science in Biology

Compared to the B.A. program, the B.S. program requires 8-14 more units of physical sciences and mathematics support courses, more focused upper-division major course selections, a senior research project, and 132 total units for graduation. A total of 36 units of U.D. BIOL is required. Students must specify and meet requirements for a particular concentration for the B.S. The lower-division core is structured so that switching between the B.A. and B.S. programs in the first two years will not delay completing either degree.
