if it's a book, then I note down key points after every chapter. if it's a video course I just passively listen everything then take a practice test, then see where I am struggling then rewatch those videos (problem is that lot of times videos are NOT worth taking notes and you only realize after the end whether video was worth it or not, so it kills me to be taking notes continuously)

best combo I found was text to speech feature of online textbook, I'd listen to it and if I found anything even remotely important I'd stop the recitation and copy the text in notepad or something, and by the end id have compilation of important notes. The act of highlighting/copying/pasting was enough to form a good memory.
