For the options part of your exam you will have to write an essay. The idea is to get your information right 1st- this is mainly the 1st 2 sections of the syllabus the key points and the legal issues and remedies. The actual essay question will most likely be from the last 3 sections- things like effectiveness of the law, morals and ethics, how the law has reformed etc. I did family last year and how I studied for this section was that once I had all the information done I wrote down key points for the different sorts of questions I could be asked like, effectiveness in dispute resolution, has the law reformed to keep up with change and these are just 2 examples. Basically once you have done the syllabus, you should really concentrate on how answer questions like evaluate or assess etc.
and dont forget LCMD.
