Right. you basically have to do 4 topics out of a choice of 5, they are religion and human relationships
religion and medical care
religion and equality
religion, poverty and wealth
religion, peace and justice
just pick your 4 best and revise them.
Get some sleep and get up early with strong coffee to revise - you'll take more in. And anyway, it's RE, you don't need it for any courses or jobs or whatever so don't worry if you fail.

Unless you plan to be an RE teacher? If that's the case then... choose a different career. x
