Notes

  1. In some areas, the Department of Pure Mathematics offers two distinct streams of courses, one for students in a Pure Mathematics major plan, and another for students in other majors. PMATH courses numbered from 345 to 352 are designed for Pure Mathematics majors. However they are open to all students. The PMATH courses numbered from 331 to 336 cover similar topics at a less intensive level.
  2. More detailed course descriptions and availability information can be obtained from the Pure Mathematics departmental web pages.
