Remembering quotations

I’m not entirely certain whether this is the right place to post so please let me know if not. I am currently doing literature GCSE with plans to continue it to A-Level. My texts are Macbeth, Frankenstein, Lord of the Flies & the AQA love & relationships anthology. My question is whether anyone has any tips for remembering quotations, particularly from the likes of Frankenstein where many quotations can be particularly long. Many thanks for any advice.
