**A major in mathematics **can be achieved by satisfying the requirements listed for either the bachelor of arts or bachelor of science. Lower division students are urged to consult a member of the departmental faculty before enrolling in courses other than those satisfying Division V requirements.

A minimum grade point average of 2.0 in courses which comprise a major or minor in the department is required for graduation with any major or minor which the department offers. Students may major in the department and minor in statistics, but the only electives that may be counted towards both programs is exactly one of MTH 121 or MTH 205. Students may not major in the department and minor in mathematics or double-major within the department.

The department regularly schedules activities in mathematics for students that enhance the course offerings. Examples are:

- Participation in the annual Putnam examination
- The COMAP contest in mathematical modeling
- The American Statistical Association DataFest
- Local chapter of the AWM (American Women in Mathematics)
- Data science and hackathon events
- Meetings of the mathematics and statistics club
- Seminars and courses which build upon the regularly scheduled course offerings
- Student research with faculty
- The Math and Stats Center provides an opportunity for students to receive tutoring in all MTH and STA courses throughout the year. Opportunities to serve as a tutor are also available.

Students who are enrolled at Wake Forest may not take courses in mathematics at other institutions to satisfy divisional requirements.
