If you are studying Shakespeare's Macbeth in grade 12 English, this is a good source where all the key and need to know, plus more quotes are. They are coloured in correlation with character, so it makes it easier to memorise. There is a description column for EACH quote, which covers what they are talking about, the aesthetic features, stylistic features, importance, and more. It is also in order of the play, so it's logical to understand and follow :) This made it much easier for me to memorise. I memorised about 80 last year (was not hard, especially with these notes), to fully be prepared for each question.
