The information and requirements given here apply to the 2021–2022 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:

Our major checklists also provide a good overview of the requirements for the degree/major of your choice.

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:

The B.A. in Mathematics or SDS

The B.S. in Mathematics or SDS

(*)CHEM 151 is recommended prior to beginning this sequence.

(**)Additional prerequisites must be met.

Note: B.S. students in either major may satisfy both the Laboratory Science Courses Requirement and the Application Courses Requirement by completing one of the Physics sequences. 

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. 

Mid-Career Writing Assessment (MCWA)

Every undergraduate degree program at the University of Arizona requires satisfaction of the MCWA. a grade of A or B in ENGL 102, ENGL 108 (for ESL students), or ENGL 109H (for qualified students) will satisfy the requirement. If you earn less than a B in your second-semester composition course, you have several options for completing the MCWA. You may:
