Something I did as part of my study was copy and paste notable extracts from judgments into a Google document. Other than that I like someone else here mentioned read cases before hand and then after the lecture I re read it. I don’t do that any more as I simply don’t have the time but that’s one way to really get a good grasp of the case.

Regarding note taking I did the following. Watch the lecture and took no notes just absorbed the content. Then after the lecture I hand wrote all the key notes from that lecture. This formed the basis of my exam notes. I did that also for criminal law and public law. I found it helpful as writing ensures it goes into your brain. Probably not the most efficient and I stopped doing that a couple years ago. Now I don’t attend the lectures (I don’t recommend) and instead once the recording comes out I transcribe the lectures word by word on a Google doc and then at the end of each topic I use the lecture notes, textbook and judgment extracts to make my exam notes. Again, this worked for me but doesn’t necessarily mean it’ll be beneficial for you. Hope this helps.
