14ci and 14cii from this year's hsc are nice (14cii is cancerous imo)
13a 2022 HSC (pretty easy but nice to do cuz it's annoying)
14b 2022 hsc
q6 mcq 2022 hsc
baulko 2020 and 2023 have some nice ones too
Algebro is cool and all but it’s expensive af for the owner I think (I don't rly waste their money) and I think it's kinda limited (like 3 prompts free idk).
Also there's worked solutions for Fitzpatrick, Cambridge, MIF, carrotsticks and most past papers
McGrathematics is peak
Dunno about science or English or anything other than math
For maths, ig watch tutorials from mcgrathematics, Eddie woo, Khan Academy, organic Chemistry tutor etc. then spam some textbook questions then spam some hsc questions
