How many power and conflict poems should i revise?

So GCSE english literature is tomorrow. I have delayed lots of revision until now since the weekend was massively taken up by chemistry. I am quite annoyed as I was made to do past papers that my mum printed out, having no time to study for geography, french, english lit or physics. Now it's the day before and I would really appreciate poems that can easily be compared to many themes. Apparently Kamikaze is a good one. What would you recommend?
