Chemistry HSC extended responses. (2 Viewers)

[x.Exhaust.x]

Are there any resources that focus purely on the extended response questions and the syllabus dotpoints that consists of "assess" and "evaluate"? Does anyone have a list they could post up of these dotpoints and possible extended response questions asked?

Thanks.

such a nerd bayan
ummm.. most of the extended response questions are just simply restatements of the dotpoints
so u just basically write out answers to these dotpoints which have the words assess, evaluate and all the other words in front of them
another source is just simply looking through past HSC papers for the big mark questions, e.g 5-8 marks
and then using the marking guidelines to do them
