Thanks... though look to the next post covering the 2020 HSC where I think failing to extrapolate will be penalised.Thanks for the very detailed response! From all the students here we all really appreciate mods and past students pitching in to help.
I suppose maybe extrapolation in this case is "acceptable" in the scope of the HSC, but not so for further studies. But I agree that its likely that NESA would negate this issue by providing (0,0) as a point if they required a plot.
Anyways, thanks again (particularly to those who wrote the BOS trials this year) for helping!!
As for the Chemistry BoS trial, that was all Jazz's work. I have offered him some feedback on some minor issues, but overall it was definitely excellent.
