Biology B.S.

The B.S. in Biological Sciences requires a minimum of 120 units, and is comprised of coursework required of all majors (see preparation for the major below) and coursework from one of four specific areas of concentration (general, ecology, molecular and cellular biology and physiology).

First-time freshman applicants must complete, with a grade of C or better, a comprehensive pattern of college preparatory study totaling 15 units. For more details, see the section on Admission Policies in the Campus Catalog.

Transfer students entering the program at the junior and senior levels will be expected to have completed the equivalent of lower-division requirements elsewhere during their first two years, including four semesters of chemistry, two semesters of physics, and two semesters of college-level calculus or one semester of calculus and one semester of statistics.

Pre-health professions students (pre-chiropractic, dental, medical, optometry, osteopathic, pharmacy, and veterinary) are recommended to take BIOL 210, 211, 351, 352, 353, two semesters of physics, and several chemistry courses.
