JOBs for Masters Students

Hi everyone , im a student who is most probably coming to the UK for masters this September! my counsellor mentioned that we are allowed 20Hrs of work time per week. I was wondering what kind of jobs I could apply for the In the time I am allowed to work per week? ill be in Surrey - London area and is about to Pursue a MSC in Supply chain management.

Jobs in that line of study Is obviously preferred but honestly anything would do so I can ease up on the finances.
