English Lit Exam

how would I revise for this? all i've done so far is learn a bunch of quotes and i'm stuck on what to do next. i know all the themes for of mice and men and im also doing an inspector calls and heroes. i have only studied for omam so far though.
any revision tips? is it like maths, should i just do past papers orrrrr?
(exam board is wjec btw!!)

thanks
