what's a good job for a uni student?

hi everyone,

i'll be studying by 2025. i had a full time job for 2 years as an admin assistant but left due to stress. and they do not allow part timers if i started studying.

im currently working as a crew member of mccas for two weeks now. but the shifts are quite few. what do you think is a good part time job if you're gonna study full time?
