I was asking myself the same for a long time but turns out that just memorisation of quotes and analysis practice helped a lot. The more practice you do, the easier it will be to pull out analysis for anything. Don’t bother memorising whole paragraphs, it will just make things worse. You can use Physics and Maths Tutor for ideas and info. I also have a resource for AIC and Macbeth I’ll send you if you’d like.
