Wow, you have 30k and still studying. What about your study, fully own money, loan or scholar ? What about transportation, possess any ?
If you're under loan, I'd suggest save up for easier to repay later. If no transport, save up for downpayment later after you graduated and looking for a job.

As for me, age 24 and seems unable to save up a lot despite living with parents, so no rental. Expenses are as follows :

Fuel RM 250
Toll RM 100
Lunch RM 150
MBB Insurance RM 41.10
Repay MARA RM 200
Tabung Haji RM 50
Parents RM 400
Personal Savings RM 200 <<-- this goes to either UT or ASB, fully untouch

Balance left roughly RM 500 - 600. Seems like alright, but at the end of the month, left ZERO. I don't spend on things, but I guess I spend a lot on weekends like cinemas, hang out and eating especially. I am not stingy when it comes to eating

You might notice no phone bills, as mine is a supplementary line under my dad. Does not cost a lot as I seldom call. Only SMSes, which not so much (I think) so my dad pays. No commitment for car, as it is not under loan.
