What San Diego expects

  • General Biology B.S. · Human Biology B.S. · Microbiology B.S.

    Courses to finish

    All Biology majors require BILD 1 and BILD 3, CHEM 6A, 6B, 6C and 7L, and MATH 10A-10B or MATH 20A-20B. Source

    Selection

    Screened major. Each course needs a C- or higher, with a minimum 2.5 GPA in these courses. AP/IB credit counts toward the courses but not the GPA. Source

    Campus rule

    Biology needs intro biology, the general chemistry series with lab and calculus done by spring, with a C- or better in each and a 2.5 GPA across them. Source

    Also note

    Marine Biology B.S. (Scripps) uses the same course list with C- or higher grades and a minimum 2.5 GPA. Source

    Every San Diego major

    UC San Diego admits transfers at the junior level only, and every transfer must be admitted to a major. Source

    Applicants to screened majors are screened on the number of preparation courses completed, the grades in them and the cumulative GPA. Required preparation must be done by the end of the spring term before fall admission with a C (2.0) or better unless the major states otherwise. Source

    Data Science, Engineering and Public Health are selective majors with limited enrollment due to capacity. UC San Diego strongly recommends listing an alternate non-selective major, and applicants not admitted to the first choice may be admitted to the alternate if space is available. Source
