I only have £25 a week for uni, Help?

I will be starting uni in 4 weeks, found out that i will only be getting £25 per week for Food, Social, Entertainment, Travel and equipment. I was wondering if this will really drastically effect my uni life where im left sitting in my dorm room alone while everyone goes out and has fun drinking or going out for meals i can't afford.
I know a part time job here is necessary but im just scared that i wont be able to get one with the thousands of students wanting one aswell.
What are the cheap food options i can go for?

Cheap food = supermarket own budget brands, raiding reduced to clear stuff and freezing, making meals in bulk to portion and reheat later... It's just about possible on £25 depending on how many nights a week you eat beans on toast :/

shopping at places like lidl and aldi are probably your best bet, and a bottle of dodgy vodka is also really cheap there, so you dont have to stay in your room the whole time. The only real way to sort the problem out is to get a PT job. and yeah there are a lot of people going for one, but theres also a lot of jobs avaliable, especially at pubs, clubs, SU, etc. get working on your CV in the next few weeks, make sure you put all your past experience etc, even send it to your past college tutor(s) if you have one/them so they can check it and improve. as soon as all the uni students move in every place with an avaliable post is going to get flooded with CV's, so try to move in to your uni flats a day or two early so you can beat everyone to the mark, get yourself noticed, and give yourself the best possible chance at grabbing a job... dont work too may hours though

Thanks for the reply! im planning on getting some work experience in bar work just before i go, what would you say are the best well payed PT jobs i could go for? I really want to have a good time in uni and not be depressed on how much i will be scavenging just to live. is there any options i can put on my CV that gives me a greater chance at getting a job than others? How would i go about apply for these jobs? Online the day i get there? or going to see the jobs office in univeristy? How many hours would you say i worked a week?
