Courses numbered 500 and above are graduate level and are open to undergraduate students only under special conditions explained in the appropriate graduate section of this publication. Courses numbered 100 to 299 are lower-division courses and are generally taken by freshmen and sophomores. Courses numbered 300 to 499 are upper-division and are generally taken by juniors and seniors.
