How can I memorise notesWatch
That's a really ineffective way of memorising them. You should be doing something with those notes and rereading isnt your method. I suggest finding what kind of learner you are and use revision techniques to memorise those notes. For me since I was a more kinetic/ practical learner I learnt through practice papers and flashcards but it could be different for you but you should be actively doing something with those notes.
