I would not practice on Fitzpatrick, (unless your teacher takes questions from there. ) But if you have a good look at some past papers from the HSC, they are basically asking you questions that involve the same concept over and over again, just in a different form. So if you understand fully each concept, you should be fine.
Thankyou! I worked my bum off to be honest so If i went to a better ranked school a 90 would have been achievable Ah well. I was thinking usyd, byt my atar is still too low for transfer options. UWS may be the best way to go
