I didn't even get a SACE.
I'm now 3/4 of the way through uni now and I've got a GPA of 6.0. School doesn't mean shit, and you will find that out pretty quickly as soon as you hit the real world. I worked for a bit then took the mature entry exam, it was ridiculously easy and I scored in the top few percentile so I had a very wide choice of courses to go with.
The best part was, working allowed me to set myself up and get proper world experience which then allowed me to approach my studies with maturity. A lot of people are very quick to throw away their studies because of terrible attitudes which have not been treated through hard work to put things into perspective. Also, having a stable job on your resume puts you ahead of a HUGE percentage of students, because most of them leave school and go straight to uni, then wonder why they can't get a job afterwards.
