I make flashcards for all of them and I revise them. when u know the key bits (e.g. harmony/tonality/texture etc) it is easy to pick out as there is 'key terminology' in each set work. melody is straightforward as u can hear it
for wider listening I don't listen to them that often, I revise the names and the key bits that relate to the set work so I can throw it in for the essay
