I think I've posted something like this somewhere near here before, but experience of a friend and others they know at Hull is that the accommodation allocation is a bit random. If you apply on the first day during the first hour possible and put Nicholson Halls as a first choice, don't assume you will get it. In fact, you may not get any of the options you have put down but the accommodation people are apparently super helpful and whatever you do get, you are very likely to be happy, so I'm told.
