More focus on case studies than in prelim. Crime is a great topic, its very interesting to learn all the components of crime. The focus studies are good in the way that you can really get stuck into the research and analysis (though it will depend on which ones you do, try and get your teacher to do Family cos its awesome).
I have really enjoyed it, but some have really hated it. It depends if you are they type of person that likes the things legal offers.
