Hi Brian,
I think preparing answers to previous exam questions is a good tactic, especially for complex questions that touch on a number of different topics. And there are topics that keep reappearing - eg rape/sexual offences, actus reus/mens rea and murder in criminal so it's worth having a good answer prepared for those areas. I think answering technique is vital in these exams too so it's good to develop that.
I think the key thing for these exams though is to have studied the entire course. To do this I read it to understand first, then read through the exam papers and reports and learn off the cases/rules/laws closer to the exams. The exam reports are very useful as they point out what the examiner wants in a particular area and show how the different areas relate to each other.
If you have to leave something out because of time, leave out a discrete topic - eg I didn't 'do' shares or directors duties when I studied company. You know then that in the worst case scenario you will be down to six/seven questions out of which you've to answer five.
If you really haven't a lot done I would consider preparing for three exams and just signing for the other. That will improve your chances of passing the three needed and you can't go to Blackhall any earlier than oct 2007 at this point anyway. Better to get the three rather than have to repeat all...I did that first time round.
Regards,
Michelle
