Easily were over 2004-2008ish.
2004 team had Barrett, Timmins, Blacklock, Gaz, Cooper, Baily, Hornby, Ryles, Kite, Creagh
And they are just the ones I can think of off the top of my head...
Year 11 Yearlies I failed Extension 1 maths (about 40%), just passed chem (51%) and maths (60%)
In the HSC I ended up with 40 in Extension 1 maths, 87 in chem and 88 in 2u maths.
Very easy to better yourself in the HSC with a good study plan.
