Apart from necessities that involve regular out goings there are things that you will be buying irregularly but can be quite expensive and you should think ahead about them and whether you really need them.
· Clothes, now there are lost of discrepancies in the law about the wearing of clothes but most of you will choose not to walk round au naturel so just remember to leave enough money aside to buy new boxers every now and then
· Music, Music is an essential part of young culture and its often very hard to resist the temptation to buy a new CD or a new Hi-Fi or whatever else you need.
· Unexpected extras, this is what will mess most peoples finances about. Examples of such things from my own experience are sports equipment, birthdays, fines, trips, books etc…
My final piece of advice would be to always leave a little extra in the bank just in case because 99% of students will go over their budget. Also don’t worry too much about your money, university is all about having a good time.
