If you have already declared a major in math or SDS, the best place to look is your advisement report in UAccess (see the My Academics link on the left side of the page in your Student Center). Your advisement report shows all of the requirements for your degree, including your major requirements. However, if you have not yet selected an emphasis for your major, those requirements will not appear until you officially select your emphasis.
The math and SDS major requirements for the current academic catalog are posted on our website:
We also maintain an archive of requirements from past catalogs, accessible from the page above. Note that students by default are typically placed into the catalog that was in place when they entered the U of A. However, students have the option to select a newer catalog if they wish, up until the degree is completed.
