Original post by Stiffy ByngI do not agree with the suggestion that a Cambridge (or Oxford) college is a "glorified hall of residence". A college is a self governing academic community. It's usually the centre of an undergraduate's academic and social world, and not just a place to eat and sleep. If a member of a college wishes to, he or she can have a lifelong relationship with his or her college. Many alumni of Oxford and Cambridge have strong affection for their colleges, donate money to them, and so on.
As noted above, however, the fact that a college is for women only does not make the undergraduate experience any the less fun. It's a college, not a Nunnery, and as a member of the university you have access to all of the colleges. When I was at Oxford, Somerville, St Hilda's, and St Hugh's were still all women, and Oriel was still all men, but that did not prevent members of those colleges from partying and taking part in clubs, sports etc with people from all across the university. I studied history at Wadham, a mixed sex college, and had most of my tutorials there, but also had tutorials at Pembroke, All Soul's, Magdalen, and St Hugh's. I attended a fabulous seminar series run by the great Keith Thomas at St John's, and joined the Stubbs Society (the cross-collegiate history club) to listen to (amongst others) Hugh Trevor Roper (returning to the familiarity of Oxford from his chilly reception at Peterhouse) give talks (and donate some fine whisky liberated from the Peterhouse cellars).
I hung out with friends, mainly at Wadham, but also at Balliol, Queen's, and Lincoln, and we partied at many colleges. I was in plays put on at Oriel, New College, Trinity, Wadham, and Merton.
I agree with the suggestion that the choice between St Andrew's and Cambridge ought not to be a difficult one. Not so long ago, the son of a friend of mine (I shall call the son John) was offered a place at Cambridge but considered going somewhere else in the UK. A family friend who teaches at Cambridge took him aside and said "John, it's Cambridge." John went to Cambridge, had enormous fun, and got a first. OP, you have won one of the top prizes in the university world. I am not knocking St Andrew's, but if you have the chance to study history at Cambridge, study history at Cambridge.
