There are a LOT more rars than I thought there would be. Complaining to mummy on their mobiles about the frightful northern weather and how (this was actually heard by a housemate) they "Can't wait to get back down to London, back to civilisation!". Like we asked them to come here. However, take them for who they are and not what school they went to and ignore the people who look down on you because they don't do the same. Their loss.
There are plenty of people who went to state schools as well so whichever category you fall into, you shouldn't feel too isolated to begin with and should be able to mingle anyway with any luck. Anyone feel free to contradict this, but I got the impression that catered blocks attract the more affluent so if you don't want to feel too common and don't mind not having your meals cooked for you like kids, go self-catered.
