Ooo biomedical science. You have to find your own niche! It took me over a year to realise how to make effective notes and it was annoying.
I write lecture notes out as I said earlier. But for anatomy (which is 100% horrid) - I draw diagrams out/just write on my lecture notes and revise it from there.
For microbiology - I make simple tables on the micro-organisms. E.g S.aures, gram positive cocci, catalase positive etc etc. Brief short notes
For histology- I draw basic diagrams out as well (and recognise the different tissue types)
Basically, explore different ways and find one that suits you best. Took me pretty long as well, but once I got the hang of it I started doing really well!
Key thing is always make sure you are organised/notes in one place. That is half the battle won!
