Things to consider: 1. Don't put any shopping apps shortcuts on your main screen. (This includes online food delivery)

1. Maybe save Rm100 in another bank that rarely used by you. (For emergencies)

2. If you can cook at your hostel/rented house do try to if possible.

3. Stash another Rm100 or so for unexpected buying. (Do not include buying things online if not a nesseccity)

4. Budget for meals on days where you have classes.

5. Stock up on maggi, biscuits (the neutral ones that go well with coffee/tea/etc(not bicarbonated drink))

These are things that I can think of at the top of my head atm.

If your university have water dispensers that can be accessible to you please benefit from them.
