Revision kick off

Hi, first of all can I just say that the course notes and, in particular, the online lectures have been a great help to me in studying for P3 and I am very grateful to the individuals who work to create and maintain this fantastic online resource - for free! Now to the question... I have just got to the stage where I have finished my textbook and am ready to start revision. I was wondering how you would suggest I start the revision phase? I have purchased the practice and revision kit from BPP so have that available to work from. Do you think it is best to work through this before tackling past papers or do you think it is of more use to attempt past papers so that I can identify areas of weakness and then focus on these in the BPP revision book? Thanks AJ
