How to revise for A level English Lit - Gatsby/Passing?

Im honestly so stuck, and i was wondering if someone could help me with how to revise for my american lit mock in April.
- what themes may come up in questions?
- revision techniques? - i like to use mind maps, how can i make use of them?

hi there, idk what exam board you do but i do OCR and for my last mock i basically did big A3 mindmaps of key themes but each branch would basically be a paragraph where i hit all the AOs. And then from this you can basically memorise key quotes, context, critics etc that you need. Hope that helps!
