Well staying in halls managing your costs is different, to if you were staying with family. Mainly because you will be more independent, and the money that you earn will be your own, not your parents. But if you budget well, then everything will fine. The main thing is knowing how much you have paid for your room, and whether or not you have finalised all the payments, then you will have to think about cost of travel. If you are living quite far from the uni, then spending a lot of money on travel is quite an easy thing to do. You will have to invest in special travel cards such as Oysters and National Rail Cards, to get cheaper travel costs. Looking for bargains at the supermarkets is also a good thing. Buy something where it is in bulk, or deals, where you buy one and you get one free, or buy 2 for 1. Every so often put some money on the side in the bank every week, such as 10 or so, to get more money for non-emergency things i.e. going out with friends to the cinema, clubbing, pub, bar etc.
