8 subjects per semester
According to my tax liability notices and my uni paper work I am doing 8 subjects per semester. At a standard 8 credit points that would be 64 per semester I guess. Which counted by the tax office as being a 1.000 EFTSU load per semester, all externally while working a full time job. I am accumulating around 6 grand worth of HECS/PELS a semester for it too.
It's great, passed all 8 last semester, hopefully do the same this semester although i've had to ask for extensions.
