Hi nessa17,
I do modern poetry too! I got an A in my mocks and I'm trying to work up to an A* in time for end of years as well.
What I find helpful for revision is making mind maps or just 3 sections of the main key themes/messages/points of each poem. After adding techniques, quotes, narrative etc., you would have a blueprint of some big ideas to compare your unseen poem to because you mostly have your topic sentences by comparing how the unseen and the anthology poem present the key themes/messages/points.
English is one of the good subjects for me, it's the others that need work - I'm trying to work up from a B for the rest of mine lol. Hope your other subjects go well too!
Good luck with your revision !!
