The answer is: this changes completely for each person and also changes for that person across time and for different modules!

Another difficulty of med school is that topics are so different to one another: one day you're revising anatomy memorising bones and muscles, the other you are working through chemical reactions in a cell, the next it's statistics with formulas and tables and then you're on to sociology and psychology writing essays! What I'm trying to say here with such different in the types of content you will have very different ways of learning and revising for each module!

Using our examples: for anatomy I loved flashcards with diagrams and testing myself repeatedly to memorise them, for chemical reactions I liked watching youtube explanation videos that were very visual and clear, for stats I would go through examples and calculations to practise, for sociology I would read the lectures or textbooks and make flashcards with key concepts.

I think the best way when you start a new module is trying out different ways of revising that content, using your previous experience, but then don't be afraid to change completely during the module to try a different method and see if it works better for you! For example I initially started taking notes for all my lectures then I would have separate notes to the slides, I realised at the end of first term that this wasn't really working out for me so I started annotating the slides directly and that way had only one set of resources. Then for some module I found I did not like the lecturer's slides style so I went back to making my own notes for that module.

I would also advise to ask your friends and people in the year above how they studies for each module, you can try out their suggestions to see if they work for you. But remember don't compare yourself, everyone's learning style is so different!
