For the actual exam you need to revise quotes from a range of characters relating to the key themes. Pick some from different acts so you have a wide range of parts of the play.
You could write yourself summaries of each scene picking key characters, key themes and key quotes from each scene. (You could put a few scenes together/skip ones where not much happens).
Can't remember what else I did for Macbeth but this helped me out with all my books.
I got an 8 overall but pretty sure that was mainly down to luck in the poetry anthology question!
