MATH 334 is Northwestern's course in abstract linear algebra, covering abstract vector spaces and linear maps. This is usually the second linear algebra course an undergraduate student would take, after a more computational introductory course.
Here you'll find exams and notes from various MATH 334 courses I've taught. Keep in mind that books used and specific topics covered may change slightly year-to-year, so take care when deciding what is or isn't relevant for a current course.
