What's troubling you about the structure? I gave details above in my last comment so could elaborate if there's something else
(E.g how question 1 will be worth 16marks, so spend 16 minutes on the question, which will 100% be based on one of the cases in the pre-release booklet- so I've prepared by knowing case facts on them- Quick, Burgess, Bratty, T, Hennessy, Sullivan, Kemp, M'Naghten). In Q1 you MUST mention at least 1 other linked case- so yes, if it's on Hennessy you can say it's distinguished from Quick)... Is that any help or did you mean something else? I think as long as we churn out case facts and link it to the question it's fine
As far as I've been told, as long as we read the question and are able to link a case to it, then we use it. So if it was Burgess on development of the law, I'd mention how sleepwalking was defined as automatism in Bratty, under 1991 reforms it's now automatism, the unfairness of every sleepwalker being labelled insane, how it's to protect the public from danger of recurrence. (Burgess would only come up directly in Q1 where you need to link 1 case only- so Bratty would be enough. It wouldn't come up in Q2 directly since Q2 is a source quote from the pre-release booklet, so allows more discretion where you could write about Sullivan/Hennessy etc.) Side note: my teacher told us to gather about 30 cases on the side of knowing the book cases, but it looks like you've done that already.
We haven't been told much about sexsomnia. And I haven't heard of a law commission booklet- is that just the pre-release booklet I'm talking about with all the cases/sources in? I hope so
Ps I'm pretty sure nobody will have past questions as they don't exist. But since q1 will definitely be on one of the 8 cases in the book- plan and practise all of those case facts/how you'd link them. That's what I'm doing
