1 A mathematics major must present nineteen full course credits (seventy-six hours) from outside the major field. 2 The standard entry-level course is MATH 101 . Students entering Sewanee with a strong background in mathematics may be invited to enroll in MATH 102 , MATH 207 , or a more advanced mathematics course. 3 Courses must include one course from two of the following three areas: abstract algebra or algebraic number theory, real analysis or complex analysis, topology. MATH 444 may only be used in fulfillment of the mathematics major requirements with the advance approval of the instructor. 4 The comprehensive exam in mathematics has three parts: A written exam covering MATH 101 , MATH 102 , MATH 207 , MATH 210 , and MATH 215 which students are expected to take at the beginning of their junior year, the senior talk, and an oral exam taken during the senior year. A student with a double major in the department must take a comprehensive exam in each major, and must take twelve full course credits (forty-eight hours) outside the major field.
