Undergraduate Program


The department offers a minor, a B.A. and a B.S. degree at the undergraduate level, an M.S. degree at the graduate level, and a certificate in biotechnology. Additionally, an articulation program that guarantees admission to the Doctor of Osteopathic Medicine Program at Western University of Health Sciences is available on a competitive basis to a limited number of students. Biology majors may apply for admission to this program after completing BIOL 200, BIOL 201 and BIOL 202 at CSUSB. Honors in biology may be confirmed upon students who successfully complete an approved independent research project and maintain a specified grade point average.

Degree Requirements

All students obtaining either the B.A. or B.S. degree are required to complete the Biology 200-201-202 core series, Cell Physiology (BIOL 300), Molecular Biology (BIOL 400), Ecology (BIOL 450 or BIOL 455), and Genetics with laboratory (BIOL 423) in addition to other upper division elective requirements. All students must pass a four-quarter series (BIOL 200, 201, 202, and 300) with a grade of 'C' or better before they may enroll in any other upper-division Biology class.

Undergraduate Degree Changes, Effective Fall 2016

Beginning in Fall 2016, course requirements for the BA and the BS in Biology will change to provide students greater flexibility in tailoring their degree. Additionally, the pre-med tracks of the BA and BS will be phased out. Students who are already in those tracks may remain in them. For more detailed information about these changes, please see FAQ for new Biology degree options at CSUSB beginning 2016.

Review the new degree requirements for the BA and degree requirements for the BS below. Roadmaps (suggested course schedules) for the revised BA and BS are also available: Roadmap for the BA in Biology and Roadmap for the BS in Biology.

Degree Options

The following undergraduate degree options are available. Please note that course requirements for the BA and BS in Biology will change in Fall 2016 and that three degree options will not longer be available (noted below). Students who have already declared one of these three degree options may remain in them.

Degree tracks that are being phased out: 

  • B.A. in Biology - Integrated Teaching Track (This track will not be available after Spring 2016)
  • B.A. in Biology - Pre-med option (This option will not be available after Spring 2016)
  • B.S. in Biology - Pre-med option (This option will not be available after Spring 2016)


Information about the requirements of the different degrees and options offered through the Biology Department is available through the links on this page. Information about general admission requirements of medical and professional schools is available under Pre-professional Advising. Information on course scheduling and sample plans for completing a Biology degree in a timely manner are available through Roadmaps to Degree.

Students who receive and 'Advising hold' from the Biology Department should meet with a faculty member in Biology for advising. Office hours for faculty are posted online and on the bulletin board outside the Biology Office (BI-302).
