I'm applying to Ox (Christ Church), Warwick, Durham, LSE (Gov and Econ) and UCL (ESPS), so plainly not going for back-ups. Basically, I plan to take a gap year if I don't get into Ox - the others are there in case things change drastically, and for the banter.
Having been basically unhelpful, I will say this - Royal Holloway is of a pretty low academic standard (in comparison), but has some pretty dank architecture. St Andrews also seems to have lower entry requirements, and is a very well-respected university, but the closest offered course is Philosophy and Economics.
