Learn key scenes, quotes, soliloquies (Romeo, and Juliet's) and monologues (Queen Mab description)
MAIN QUOTES "Romeo, O Romeo wherefore art thou Romeo" - Juliet, "My only love sprung from my only hate"- Juliet.
Poetic devices- oxymoron, dramatic irony, personification, similes, metaphors, etc.
Your own, opinionated answers- opinion, quotes, formal language
learn off a the protagonist, hero, villain, a relationship, opening, closing and climatic scene and be able to describe each using a single word which can be backed up with a quote and learn how you would stage them
Pick out key quotes and stick them on your wall. I did this for my play and novel and it saved my life because every time I looked at my wall I was learning quotes. It severely limits your study (which nobody will ever complain about)
