Hello,
If your course is not very heavy, you can find a part-time job in retail, leisure, or tutoring if that is something yo are interested in. If you are a full-time student with things like placement, it would be difficult to find a part time job and so I would recommend a zero hour contract, you can pick jobs when you are free.
In university, you can work as a student ambassador and pick up shifts when you are free. Your best bet would be to check Handshake (a website where universities share their job offers).
What sort of job are you interested in ?
Best wishes,
