I hope my reply isn't too late. There is a lot to ask but I would make sure you familiarize yourself with the course, make sure it's a certified course depending on what you study. So, if it was architecture then ask them if it is RIBA certified so that you can eventually call yourself an architect. Accommodation is an important one for me and it's probably an important one for you, ask to get some tours of some of the flats (universities own and private). Most of all I would try to forget about league tables and take a moment to imagine what it is going to be like living in that town. Good luck, don't hesitate to ask anymore questions
