How to I revise for literature??

I'm doing AQA English literature and doing Withered Arm, Of Mice and Men, The Woman in Black and Much Ado About Nothing.

I think I'm alright with Shakespeare and OMAM as they give you the extracts but I really don't know how to answer TWINB and WA cause I have to look through all the book/stories and find the right quotes or words to analyse. Like, for example, how does Hill create a sense of horror in The Woman In Black, like how do I even find the things that show/create the sense of horror?? There's so many words and chapters. I know how to answer this question, as I already done in lesson, but obviously it's not going to come up again so it's pointless. The techniques and facts I learned for this question are not going to help for other questions. So how do I start? How do I find the right quotes/words so that they answer the question??
