AS English Literature- WJEC - Oleanna help D:

I am really confused about the LT1 exam, particularly Oleanna, I just don't know how to structure and answer, and how to write so much on each of the themes, and break them down into different topic sentences. I was going to go through the whole play and annotate the different themes, and then do papers, but should I just start doing all the papers now and plan essays?

If anyone has any notes or A Grade example essays could you please share some tips/send me some resources? if you wouldn't mind, also if anyone has anything for poetry (I'm doing Heaney and Sheers).

Thank you!
