You should go :) there are a lot of friendly faces out to help you and it's at least gives you a bit of a familiarity of where everything is around UTS
You can try and contact student services and see what they can do or you can ask to get your exam reviewed.
But really there's not much you can do. It also depends on how much you failed by as well. Good luck though!
I live near Mt Druitt and I'd have to agree that there are plenty of bogans here. Apparently Mt Druitt has been labeled the worst suburb in Sydney.
Fortunately i didn't go to school around here.
