We recommend that students interested in pure mathematics consider a broad selection of courses in order to be able to judge their own interest and affinity in doing mathematics. Some upper division classes are offered as Directed Seminars. You can also arrange Independent Study courses with faculty if your area of interest is not addressed by regular course offerings. Majors should consult the department if they want to complement their math education by participating in an Oxy Abroad program. Graduate schools have foreign language requirements which might vary.
Some schools prefer French, German, or Russian to other languages.
