Any predictions for the romeo and juliet question,to kill a mockingbird or studied poetry? What are the main things people are studying?!
For Romeo & Juliet, if you know the characters, scenes and themes well, you're good. Also know quotes and don't forget to use them in your answer. Use adjectives to describe your characters as well and terminology e.g three dimensional character, climax of the play etc.
For TKAMB, be familiar with characters, scenes and themes again. Learn about the significant moments/scenes of the novel.
For poetry, learn the imagery, poetic techniques and themes of the poems. Also learn what poetic techniques actually mean so you can point them out in unseen poetry
