Hi! I'm in Year 13 doing English Lit as well. I do 'The Handmaid's Tale', 'The Kite Runner', 'Blake Poetry', 'Othello', 'Death of a Salesman', and 'Keats Poetry'.
For poetry, particularly the Blake poetry, which has around 30 poems, we've all been told to split each into themes that potential questions could be on, so things like 'Blake as the champion of freedom' or 'the abuses of the education system' and then create a hierarchy of poems, which can be used in each section, and then basically forget about the poems that have limited use.
I don't know how it works for you, but for me, 'The Handmaid's Tale' is open book, so most of my revision for that is remembering key scenes that I can use to make things quicker in the exam. So, for example if it was a question on rebels, then I'd turn to Offred talking about Moira's escape from the Rachel and Leah Centre.
Most of my 'Othello' revision is making essay plans and learning quotes related to themes, like 'the role of women' or 'Othello as a tragic hero'. I have many debate essay example questions if you wanted me to put any on here?
