### Course Numbering System:

The first digit of the course number indicates the level of the course: roughly, 1 and 2 indicate underclass courses; 3 and 4, upperclass courses; 5, professional-level and mathematics education courses; 6 and 7, graduate courses. Within the MATH subject area, the second digit often indicates the subject matter: 0, general; 1 and 2, analysis; 3 and 4, algebra and combinatorics; 5 and 6, topology and geometry; 7, probability and statistics; 8, logic; 9, other.

### Courses with Overlapping Content:

Because the department offers many courses with overlapping content, students must choose their courses carefully to ensure that they will receive credit for each course they take. Forbidden overlaps are noted in the course descriptions.

Courses with overlapping content are not necessarily equivalent courses. Students are encouraged to consult a mathematics faculty member when choosing among them.
