Prerequisites and corequisites for a given course indicate the background subject material that is required in order to be adequately prepared to take that course. Students who do not have the course prerequisites and corequisites will not be permitted to register in the course.
Many students are unable to take desired courses in later years because they didn't take prerequisites in early years. The prerequisite map can be used to guide your course selection. Please consult the official Arts and Science Calendar, as prerequisites can change.
