Every student at Cambridge University is a member of a college. All colleges admit graduate students, but at some colleges, undergraduates make up the greater proportion of the student community. Clare Hall is a graduate college renowned for its informal approach to college life and international diversity. The President, Fellows, Visiting Fellows and graduate students together make up an integrated academic society that is not constrained by hierarchy and is consequently a culturally rich and intellectually diverse environment for advanced study. Graduate students are admitted by a University department to study towards a variety of post-graduate degrees, but this is subject to their acceptance by a college.
