How do you memorise so many quotes
Do teachers not like shorter quotes (1, 2, 3 words)?
What do you do if you forget?
actually they do like shorter quotes - or if they're too long they'll recommend you shorten them, at least in my case. the longer your quote is, it can affect clarity, which can be confusing to your marker.
in terms of memorising quotes, i just recite them. i'm someone who memorises the whole essay to bring into the exam so all i do is in the few days before the exam (even 2 days before because that's what i did for trials) i just walked around my house reciting the words to my essay. i have a few friends who just wrote down quotes and recited them on their way to school and ended up memorising them. i find with shakespeare, it's slightly easier because of the meter it's written in and because it's in a dramatic form, and there are certain 'popular' quotes the teachers bring up a lot and kids use a lot so they become more ingrained in your mind (eg. for merchant of venice, a popular quote would be portia's monologue on christian mercy - 'the quality of mercy is not strained / it droppeth as the gentle rain from heaven...') reciting them and practising writing your essay helps your essay get stuck in your mind. like, it's been around a month since i did my trials for paper 1 but i still remember all my quotes and most of my merchant of venice essay.
it depends on what you forget. i memorised an essay but when i wrote it out i realised i forgot the full quote and that part of my analysis didn't make sense for the q. i had a few random quotes from the back of my mind (for example super short ones that stick out like shylock's very last line in the play - 'i am content'), so i replaced the forgotten quote with that one. if you know the gist of it and know a few key words, just make it up - just don't make it super outlandish.
