Trinity, Johns, Emma, Jesus, Caius, Catz, Christ's, Peterhouse, Magdalene, Corpus, Kings, Downing, Pembroke, Sidney, Clare, Queens' - these are generally perceived the more prestigious (i.e. all the central colleges...).
Is there a way to change colleges once they have been allotted at the Camrbidge University?
Any suggestions will be greatly appreciated.
No, not unless there are "exceptional circumstances" (and I have no idea what an example of those would be). I mean, if they allowed people to change nobody would be left at, ahem, *certain* colleges, would they?
It depends what you're looking for. Jesus has some of the nicest grounds around - it's all very green! I love Downing's architecture, but you might prefer the wierd charm that you get at Sidney Sussex. Robinson is pretty fugly though.
The only way to decide is to get yourself down there and have a proper look.
