Hiya, Case notes are just summaries. I always started with very very basic bullet points, like atime line of the case and fill it in. for instance:
Mrs Donoghue drank a ginger beer that had a snail in it and became ill
The cafe owner did not know the snail was in the bottle.
and so on. Like rip the judgment up into very small facts. you can finesse it then, out more meat on the bones as such.
Not sure if you will be able to follow this link, but this is from the OU law faculty.

This is very true. I'm currently advising in a law clinic, and the difference to reading law etc, but dealing with real problems is night and day. Still need to know how to play the game etc though, and get the degree in the first place!
