I suppose if your willing to take the risk... I did for the trial and they gave me the exact questions I prepared for so I ended up getting 49/50lol, to all you people who say it's stupid- I'm going to do it anyway. I got 85 in the trial doing that, got about 46/50 for the essays section if I recall correctly. Yeah, I know, risky. But due to time constraints I'm taking it, it's not difficult to bend arguments if you're just a little flexible with your knowledge.
but that was because I had my teacher's assurance that "we shouldn't worry" and it wouldn't be very different to the one's we did in class, so I think I won't take the risk for HSC
