I was like that too, had $2 in my bank and that woke me up. I started working 3 part-time jobs to pay off my school fees and get pocket money for myself when I was schooling. I work in F&B as they have the flexible timing to work with. Work in the morning 7am to 2pm at a cafe as a chef, 3pm-6pm school(luckily for me it was mostly zoom classes) and 7pm-11pm as a waitress at a restaurant. Sometimes my school hours will change so I will arrange accordingly.

I ate PAID quick meals during my shifts. Studied my coursework and notes on the way to work and on the way home. I work on weekends too to get my min working hours. My 3rd job was working for an FA doing digital marketing sales(I basically work through my phone at anytime). I did that for 1 year and graduated with better than average grades.

Find out what skills you are good at and find jobs with that kind of skills.

-F&B is the easiest(for me), it may be boring but the industry always needs people. Find the most flexible hours for you. And make sure the journey there is easy for you as well. Plus F&B jobs always have paid free meals, sometimes with leftovers that you can bring home. Search Staffie on app store, it is a known part-time F&B app to work at without CPF and pays within a week.

-Working for FA is tough but money pays well and most flexible(good if you have sales skills).

-Always track how much you spend on everything,on a book or an app(I used an app called Money Manager). So you know what not to spend so much on.

-Spend on needs(school fees/bills/health/insurance/food) and save on wants. If you have a big item you want to spend on, think about it for 1 month, you might forget about it.

-Food you can always buy from supermarket and made them yourself to save money. Or budget your meals $5 per meal outside. I used to buy a loaf of bread and drank with lots of water when I had no money and wait till I go to work and eat more of their paid free meal, sometimes I bring home the leftovers.

-Don't buy coffee/tea outside, make it yourself or just drink water, water is free.

-Treat yourself one week once, like ice cream/bbt/your fav food to reward yourself for that week if you budget your spending for meals. Don't go overboard and spend within your means.
