i didnt understand this question exactly as many students of CA Final had asked this.. Dear you are in CA Final ... you now are strong enough to suggest others how to start a subject .. stil u asking same... why so...

now when u had asked this i must say... start from the basics which u had studied in ipcc like capital budgeting cost of capital etc etc... and move on..

You can study from module plus practice manual plus rtp 

the more you wil practice the more you wil b perfect...

One more thing make a Formulae copy before you start any topic. Write all formulaes chapter wise in that copy along with some important points which u thik is necessary for you...

Weekly revise that copy so that u can wel grasp on the formulaes...

All the best
