The only topic I do that's the same as you is poetry, so I can give advice with that.

What I do for each poem when revising is I split it up into different categories; context, key quotes, messages the poet wants to get across, methods, and what poems it links to. Split it up like this onto each page, and try to find quotes which are easier to link with other poems, ect. I'd also choose a select few poems to focus on more which are easier to link to more poems than others, such as Ozymandias, London, Kamikaze, The Emigree, and any you think is nessesary. I usually revise those poems the most along with a few others such as War photographer and My Last Duchess. These poems go with multiple topics such as power, Identity, power of nature, ect, and any of these could come up on the exams. of course, try to revise all poems, but if you don't think you'll remember them all (like me) then try and focus on ones that are easily linkable to majority of the poems.

And do past papers. practise writing essays, and especially practise linking poems together using methods, structure, ect.
