Wasn't that the one with the crystal and you needed to find the rate of change when t=1?

Premiers you need 120/120, for a 50 119/120

Well the Arc length formula was on the formula sheet, so I plugged in the given equation into the formula, hopefully that gave me the right answer

you can get a premiers award even if you lose 1 mark. it just depends on how well the state does. i lost 1 mark overall and got premiers for spesh. raw 50 depends on how hard the exam is overall. generally you can lose 1-2 marks overall and get 50, but depends on how easy or hard the exam is.

If you were to make one arithmetic error at the very beginning of the question worth 3 marks and did everything else right would you lose just 1 or 3 marks?

probs 2

Would i lose marks for leaving the weight force on the first question as mg instead of 20g? Also misread the last question and integrated rt(2-x) instead of rt(2-x^2) how many marks would i lose with the right workings?

IIRC it was out of 5, probably 2; one working mark for evaluating the wrong integral, then another for the answer unless it's somehow correct anyway.
