[BOC]
Usually at high school or college. You know, like people selling snacks from classroom to classroom.

One of my friend works night-time to pay for her school and her money (she didn't given money for jajan anymore by her parents) at 11th grade.

Vocational high school have 2-month internship and 2-month freelancing (for certain specialties, usually IT-related field such as Multimedia or software engineering).

But not everyone works part-time at high school and it's not really a culture. Most people I know work part-time at the college.
