I'm a mature student, who is self teaching and will be applying to uni this year. I need to save around £2k in order to sit my A Level exams and practicals privately, but I've been struggling to find a part-time job(~16-20 hours). I've already saved £1k from a previous job, so I've been considering investing in a bike and working as an uber eats/deliveroo driver. I've heard that the pay is pretty bad and that it's quite an unstable job, but I'm running out of options and time. It's a bit of a gamble since the money I spend on a bike could go towards my exams. My other concern is getting my bike stolen. Thoughts?
