There are four matters to concentrate on. For each topic (for example -doctrines such as - Separation of Powers; Rule of Law; Parliamentary Supremacy : or criminal offences such as Homicide; Theft; Rape; Attempts....) make sure that you can succinctly deal with the key
Could you describe and explain them to an intelligent friend? or deal with any question that they might fire back at you? (this is the value of working with other students as you prepare). Could you make a coherent argument in response to a request to discuss the strengths/weaknesses of the existing law - or for/against reform?
Are you confident that you know; could explain and use the relevant legislation or cases?
The diagram below might help you prepare your thoughts. [CLICK THE PICTURE FOR THE FULL SIZED VERSION]
"Condensing" is an important part of revision. [so you could review the topics and draw a diagram like the one below for each specific topic].
So is rehearsing explanations and arguments.
Is there a flow diagram you've seen - or could construct to logically set out your argument or solve a practical problem? (My students can use the Judicial Review diagram (W201) as a starter).
Are there any tables you could construct which summarise arguments - with a column for Strengths (with a second column for your evaluation of those claimed strengths) and a column for weaknesses (with a fourth for evaluation).
For Criminal Law you could draw up a table setting out in columns the Actus Reus; Mens Rea; and defences for each offence, along with the leading cases and a sentence to remind you of the key facts.
Revision is not about memorising lots of facts - and regurgitating them. It's about demonstrating your handling of the concepts; arguments; and authorities. Train for the exam, not like a child preparing for a spelling bee competition, but a football player - ready to flexibly respond to whatever strategy the opposing team uses on match day. Flexibility and skilful use of your acquired resources (your knowledge and understanding) are the key.
