I wouldn't say to learn off answers but definitely know points about your characters, novels, play, poems etc.
Learn a few quotes from romeo and juliet that are broad enough that they would work to support any point.
Learn quotes from your novels aswell.
Know the characters in your novel aswell, character questions are really popular. know quotes to support what youre saying about them. Also know the theme of your novels really well.
In all honesty for my English junior cert last year I had a teacher who didnt teach us any english at all for the 3 years. She just talked about her life. I learned 5 quotes from Romeo and Juliet and 3 or 4 poems. I read a quick note on my novels for like 10 minutes and i got a distinction. So if i managed that without doing anything then you'll be fine. Don't stress and good luck xxx
