Durham and Edinburgh are far more rah than Oxford. All my friend at these universitis, not to mention their facebook photos, confirm this.
The reason for this is that being at Oxbridge is determined by intelligence, which is little to do with how rah you are. Durham, on the other hand, is different. There are enough universities of a similar academic level to it to allow students to pick among them based on characterisitcs like how rah the student profile is. Many students get offers from academically similar universities like Edniburgh, Durham, Nottingham and Imperial; the more rah ones will gravitate towards the former pair, the less rah ones towards the latter. That's why friends of mine seem to go entire days without meeting anyone from a state school, and keep thinking they're getting deja vus because all the girls wear the same bloody outfits.
