I have saved around 1000 bucks for just this semester for my camera/lense and films.
I was not abstemious at all.
That means u can get at least 2k for a year. Then if you only go back home once a year, the ariticket is about 600sgd, you still have 1400 left.
You'd better notice that only after you entered university, can you save money easily. During my bridging curse time, tt 250bucks per months is not enough for me at all.
saving is not easy, you must be veri determined and managing.
