A concentration in mathematics consists of the courses 116, 216, 224, 314, 325, a Senior Seminar, and three electives, of which at least one must be at the 300 level or higher. Concentrators fulfill the Senior Program requirement by taking a Senior Seminar. It must be taken in the fall of the student’s senior year, and all lower-numbered required courses, with at most one exception, should be completed prior to that time. Physics 320 or Physics 325, but not both, may be counted toward the concentration as an elective at the 200 level. Beginning with the class of 2020, students concentrating in Mathematics must satisfy the Social, Structural, and Institutional Hierarchies requirement by completing one of Math 252, Math 498 or Educ 350. Students who have not completed one of these courses may petition the department to accept a course in another department as fulfilling the SSIH requirement by providing a written rationale explaining how the proposed course will help them gain an understanding of social, structural, and institutional hierarchies that is relevant to mathematics and their post-graduation plans.

Students may earn departmental honors by completing courses that satisfy the concentration with an average of 3.6 or higher, by taking a fourth elective that is at the 300 level or higher, and by making a public presentation to the department on a mathematical topic during their junior or senior year.

A minor in mathematics consists of 116, 216, 224 and two mathematics electives.

While all mathematics courses satisfy the QSR requirement, students seeking an entry-level course only for this purpose are encouraged to consider COLEG 105S: A World of Impending Disaster.

For students matriculating before 2013:

A concentration in mathematics consists of nine courses including the required courses 113; 114, 115 or 215; 224; 215, 231, 234, 235 or 253; 314; 325; 437; and two electives, of which at least one must be at the 300 level or higher. Concentrators fulfill the Senior Program requirement by taking 437. It should be taken in the fall of the student’s senior year, and all lower-numbered required courses, with at most one exception, should be completed prior to that time. Physics 320 or Physics 325, but not both, may be counted as a lower-level elective toward the concentration. Students may earn departmental honors by completing courses that satisfy the concentration with an average of 3.6 or higher, by taking a third elective that is at the 300 level or higher, and by making a public presentation to the department on a mathematical topic during their junior or senior year. A minor in mathematics consists of 113, 224 and three mathematics electives. One of the electives is normally 114 or 215 and at least one of them must have 224 as a prerequisite.
