On the concepts front, looking at past papers there is some overlap as some concepts have appeared twice in a row, however only 3 past papers are available. Personally, I have my money on Law and Justice and Balancing and Conflicting interests. Morality, Fault and Judicial creativity came up last year, Balancing and conflicting interests, Justice and Fault the year before and Justice, Morality and Judicial creativity the year before.
Also, regarding unit 03, the most likely evaluation q is on murder/ voluntary maslaughter. Non fatal offences came up JUN13, JUN12, JUN11, defences came up JAN13 and JAN11 and fatal has only come up JAN12. So it's most likely fatal.
