In my experience, yes, but this was during internal assessments, and I haven't seen an extract in any past HSC papers, so whilst it's unlikely, I wouldn't rule it out. That being said, I wouldn't bother memorising quotes; I would just make sure I understand the core concepts of her suite and its context, which basically equips you in case they do give an extract. But I also think the likelihood of text-specific questions is highly unlikely. Overall, just make sure you know your texts and authors really, really, really well. Sorry if this doesnt help!
