If you mean stimulus tasks-
I would encourage you to do 3 things.
1. Make a list of language/visual techniques and their definitions, include some niche ones. Memorise these.
2. To get a feel for how to structure your responses, look through the answers of this paper:
https://syllabus.nesa.nsw.edu.au/as...ons-new-hsc-english-adv-paper-1-exam-2019.pdf
You could also buy a past student's responses if you still need guidance.
3. Do past papers! You can find these on BoS but just look up 'english HSC paper 1 trial' and theres heaps
Get your teacher or tutor to mark these papers if u can. Don't use up all the past papers, save some for the lead up to HSC, hopefully though by the time you guys do it some 2020 trial papers will be up online.
