obviously it depends on the question but for attempts talk about the common law tests and make sure you say the problems with them then bring in the fact that the attempts act didnt remove the common law tests so in theory they can still be used which obviously equals a lack of clarity and confussion for jurors as well as everyday people
Then you want to go on to say that there is no proper definition of what is more than merely preperation so again this isnt clear.
After the above say that if the law is meant to protect people then Ds in cases such as Geddes would be guilty so this is also an area that need improvement.
Then you can say about omissions and attempts i.e. the act says an act is needed yet there is a clear exception.
You also have attempting the impossible how Anderton v Ryan was wrongly decided and went against the act and then less than a year later it was overruled by Shivpuri by using the practise statement (include this as its synoptisity and will put you in level 5)
hope this helps!
