If you have time outside of your studies, you might consider getting a part-time job. Obviously, this will allow you to have more money, for either the essentials or to fund the nights out that many students love.
There will likely be a number of opportunities, either within the Students’ Union (SU) or local businesses and shops, to work. Supermarkets are always a good option for a part-time job, as they offer reasonable wages and you may be able to get a transfer to a store closer to home at the end of term.
Restaurants can also be a good choice, as these are usually evening shifts, and can have additional perks, such as free food and tips. Bars and nightclubs can also offer similar experiences, including discounted drinks.
