A number of courses in the curriculum require students to take and pass a course or courses prior to enrolling. Observing prerequisites is the responsibility of each student. Failing to observe prerequisites for a course may result in the student being dropped from that course and issued a W grade. If students complete a course for which they have not fulfilled the prerequisite, they will not be allowed to graduate until they take and pass the stated prerequisite. Waivers of prerequisite requirements are subject to the written approval of the relevant department chairs. Written approval must be filed with the Office of M.B.A. Student Services prior to starting a course requiring this approval. Refer to the Course List and Descriptions section of this catalog.
