Programs - Overview

The Department of Biological Sciences offers the Bachelor of Art (BA), Bachelor of Science (BS), Master of Art (MA), and Master of Science (MS) degrees in Biological Sciences, a minor in Biological Sciences, and Certificate in Issues in Natural Resource Management. Details on all of our programs can be found through the Program links in the navigation menu.

Bachelor Degrees in Biological Sciences

The Bachelor of Arts (BA) and Bachelor of Science (BS) degrees have the same core course work, but the BS degree requires an additional 12-19 units of upper division units, depending on concentration. In general, those graduating with the BS degree are well prepared for graduate school in biology, while those with the BA have the flexibility to select additional courses outside of biology to prepare them for careers that require greater breadth of preparation.

Biological Sciences pre-major

Entrance to the Biological Sciences major requires the completion of pre-major course work criteria (outlined below).  Students who have not yet completed these requirements but intend to pursue the degree will be designated "pre-Biological Sciences" until they have successfully met the major acceptance criteria.  Once they have met the criteria, they will automatically be matriculated to Biological Sciences majors.  Due to the rigor of these criteria, not all "pre-Biology" students will be successful in meeting the requirements, and it is hoped that this will assist some students in identifying other pathways to a baccalaureate degree.

Criteria for acceptance as a Biological Sciences major

  • a grade of 'C' or better in the prerequisite courses: BIO 1, CHEM 1 A, BIO 2, STAT 1 and GE Area A2, Written Communication (3 units from ENG 5, 5M, 11, or 11M)
  • a combined GPA in these courses of 2.5 or better (only first or second attempt will be considered for the above courses)
  • completion of at least 30 units of college course work
