B.A./B.S. in Mathematics or Statistics & Data Science

The information and requirements given here apply to the 2018–2019 catalog. For other catalog years, please consult the archive.

Upon declaring a major in mathematics or statistics & data science, students must select a degree in which the major will appear.  We offer your choice of a Bachelor of Arts (B.A.) or Bachelor of Science (B.S.).  

These degrees have many common requirements, including minimum units, English composition, and many of the general education courses.  There are some differences, however.

Below, you can find the requirements specific to the two degrees. For requirements specific to each major, regardless of degree, see:

Comparing the B.A. and the B.S.

As far as the mathematics or statistics coursework is concerned, the B.A. and B.S. are identical. 

The requirements for the two degrees differ only in the following ways:

  • Second language requirement (details below).
  • Science/application course requirements (details below).

The B.A. in Mathematics or SDS

  • Language Requirement: Students must demonstrate fourth semester proficiency in a second language.
  • The degree is not science-intensive. Students need to complete only the two Tier One NATS (170) and one Tier Two Natural Science courses, as specified in the University General Education requirements.

The B.S. in Mathematics or SDS

  • Language Requirement: Students must demonstrate second semester proficiency in a second language.
  • Laboratory Science Courses Requirement: The degree is science-intensive and requires one of the following sequences of laboratory science courses:
    • PHYS 141& either PHYS 142 or PHYS 241
    • PHYS 161H& either PHYS 162H or PHYS 261H
    • CHEM 151& CHEM 152
    • CHEM 141&CHEM 143&CHEM 142&CHEM 144
    • CHEM 161&CHEM 163&CHEM 162&CHEM 164
    • MCB 181R& MCB 181L& ECOL 182R& ECOL 182L
    • PSIO 201& PSIO 202
    • GEOS 251& GEOS 302
    • GEOS 251& GEOS 304
  • Application Courses Requirement: (This requirement does not apply to the Mathematics Education emphasis.) Students must complete at least six units coursework that applies advanced mathematics or statistics to other academic fields.

For mathematics majors, these courses must have a pre- or co-requisite of at least Calculus I (MATH 122B or higher). Choose from the following:

Double Degrees

Students pursuing a second major that has a degree title different from that of the first major are technically double degree students. Additional requirements may apply to double degree students that do not pertain to double major students (students with two majors that have exactly the same degree title). See an advisor for details.
