Revison For English Poetry, Business Studies, Relgious Studies.

In a weeks time I have a Business Studies, Religious Studies and an English Poetry Exam. I'm not sure how I should revise to pass this exam. If you have any opinions please post below. I really want to pass this and I need as much help as possible.

I've just started basic revision from reading the books I was using in school and I find that this is not very good.

Thanks
