I suggest you talk out loud and talk as if you were explaining to someone. Also, I saw results with using colors in your notes. It often happened that I remembered stuff because I remembered I wrote them with a certain color 🤗
Explain to other people and try to make them understand what you are talking about,even if they have medical knowledge or not.
Read a portion and memorise it, then make notes with what u had memorised in ur own words without looking at the book.
