Final costing theory

Hi,

I need suggestions on where to read theory for CA Final Costing.

I am considering options :

1. Practice Manual - Kind of reluctant because questions are distributed throughtout the PM and not very easy to find at once. But highly reliable.

2. I have Paduka - Organized and theory questions are at the beginning of each chapter. Dont know the exam relevancy of the questions there. On a prima facie look it looks there are many questions there.

Any siggestions what I should do ? Or does any one have any soft copy of any other material which is very exam oriented and in easy to rememeber format type, like Munish Bhandari handbook type lol ;)
