Same I too am doing the unseen poetry exam this summer.
Although I'm not sure what cluster in the anthology I'm doing, however I recommend that you revise by using revision guides. Find an unseen poetry book, like CGP book: AQA Anthology Poetry cluster: Conflict -and choose your level higher/foundation. With that book look at the poems but don't read the analysis on the pages, just find that same poem online, print it out and practice annotating and writing a response. When you have completed your annotation of the poem and wrote an essay on it, find the poem in the CGP book and look over the notes they made in that, then compare their work to yours, see what you got right and what you missed. Then practice another one, the more poems you can do/practice the better. In the essay about the poem if you need a practice question, just make some up yourself or find a question in the revision guide, for that poem.
I hope this will help
