Hello Friends

I have appeared thrice for group IInd of PE 2 but haven't been able to clear it and I think the main reason for this is the Costing and FM paper. I have got lowest marks in  this paper in all my attempts. It seems that I can't complete this paper in 3 hrs. I request you all to please suggest me how to prepare this papaer? I'm preparing for May 08 exams. Would you suggest any book ? Please reply.

Thanks.
