Universities usually have a hardship fund for students who find themselves in financial difficulties. If you have already signed for your accommodation etc then I'd advise to go ahead with it and when you get your money through and pay your first lot of rent, set a budget and stick to it. I had a similar amount to you between payments and it worked out at about £50 per week to spend on food, leisure, whatever else.
Some of my friends changed their budget about a bit, so if they had a birthday coming up or something, they'd live on less one week to save up for the following week if that makes sense. So if their budget was £50, they'd live on £30 for one week then have an extra £20 for the following week, meaning they have £70. So for you if you have a night out coming up, just be less spendy the week before - buy cheaper food etc.
If, like me, you can't stick to a budget, another one of my friends sentt his entire student loan to his mum who then set up a standing order for him to receive £50 of it every Monday so he had no choice but to stick to it.
So they're a couple of ideas to help you stick with a budget.
If, however, you find the budget isn't enough, speak to the university and ask about the hardship fund, but give it a go first
One thing I'd advise is to avoid a student overdraft, I racked up a big one and if I could go back, I'd budget instead. Obviously dip into it a little bit every now and then if you become a bit unstuck but don't go too far into it.
So, in summary, learn from my mistakes
It is possible.
p.s. If you get your job transferred, that'll help tremendously
p.p.s. Make sure you look for a good value student house for your second year as they are significantly cheaper than halls
