Academic potential is the main criterion for admissions, and in looking for it the College takes the particular circumstances of each candidate carefully into account. The College stands on two sites. Harvey Court, built in 1962, is just across the river, seven minutes' walk away, very close to the University Library and the new Arts faculty buildings. Although divided in this way, the College acts as a single community, and all Fellows and undergraduates take their meals together in the College Hall. Undergraduates are offered accommodation throughout their course, in College for the first and third years, and in hostels near the university cricket ground for the second year.
Most rooms are bedsitters, but there are also many two-room sets.
The College's undergraduate community enjoys a full range of social and cultural amenities. The Musical Society promotes regular concerts given by the College orchestra and smaller groups, and there are several practice rooms as well as libraries of chamber music, vocal music and records. There are debating, drama, film and many other societies. For sports, the College has its own boathouse and large playing field, both conveniently sited. The Caius Fellowship is large which ensures that undergraduates receive much of their teaching within the College.
