DT and cost Paduka answer formats?

Other books are for refrence & understanding,
anyways I strongly recommend to follow only ICAI's methods of Presentation. 

Yes you can follow tabular formats.

I suggest you to complete padhuka books as per their own formats so that you will get enough understanding and when you complete the padhuka book solve PM compltetely.

so, what i mean to say is practice and understand from padhuka and give ICAI shape to same questions.

But its ok even if you use padhuka format. its good. and used by most students.
