preparation strategy

For Auditing, you can refer VK Agarwal (for detailed explanation refer paduka)

For Accounts, you can refer MP Vijay Kumar/Paduka

The referwence books sugegst by Lavanya Daggupati  Is right .

In addition to that you should also go through module for Ad Accounts.

paduka is really very dificult to cover

the suggestion that refer v.k aggarwa sounds good for audit

and for accounts MP Vijaykujmar is really the best

 For Advance Auditing VK Agarwal (Pune) is best one.

And for Advance Accounting, MP Vijaykumar is best. I have used the same for my Finals and i didnt feel any need to join classes for Accounting. I just did self study from MP Vijaykumar.

I have done praven sharma book but if u running short of time stick to compiler and study mat .

Good Luck.
