I'm doing the same thing engineering/ arts - international studies
yeah on a student visa you can only work 20 hrs a week
excluding holidays :)
but right now I'm working part time and trying to save as much as I can so I can support myself while I'm on exchange
My hometown is also sydney, i live just about 10mins from UWS
but i'm not going there, I've chosen to be out of my local environment... too many bogans in Mt Druitt
I worked 1 - 2 shifts a week throughout my yr 11/ yr 12 and more during the holidays. But i obviously i took time off during exam time.
You just need to learn how to manage your time effectively
