Urgent help for ama

Hi Guys,

I planned to sit for both groups in this May 2015, the first group was not gone good. Today's paper of Law was good good and expect 60+, keeping the fingures crossed :)

I am very concerned about Second Group, very tensed about Costing Paper. What should be the strategy to score 50+ in this paper, my remaining papers of 2nd groups are prepared but not able to do costing properly.

Please help me with the nice strategy so that atleast 50 can be scored in this costing giant.

Please advice friends, its very important.

Regards
