CA Final-Costing-Help Required

Dear All,

I am appearing for CA Final Group 2. On May 10, I have to appear for Costing exam.
I am pursuing CA Final again after a gap of 7 years. In costing--I have forgotten everything

Please tell me what needs to be done to get decent score. I understand and will do theory thoroughly which is of 20-25 marks. Please suggest what else needs to be done to pass this exam.

My email is--gauravmalhotraindelhi @ gmail.com

Thanks a lot to all of you and All the Best to All, God Bless
