DS finished his Extension 1 and 2 Higher School Certificate maths in Year 9 and it wasn't going to be an option that he go three years with no maths.
I spoke with the school and they acknowledged that it wasn't a suitable outcome so the Principal approached the local university and arrangements were made for him to enrol as a external student in a BSc. The agreement was he would concentrate on completing only mathematics units initially and as time progressed branch out as he desired.
He started with one unit per semester and attended residential schools where appicable.
As he completed further school subjects ahead of time he picked up more university units. By this time he was driving so he pretty much spent the last two years of school splitting his time between school and attending lectures on campus.
His enrolment at university did not affect his entering mathematics competitions here although he did lose interest in them so rarely entered.
