How to prepare for auditing?

Firstly advise you to refer your coaching material, if you have undergone. If not, then you may buy either Vikas Oswal IPCC audit book or Surbhi Bansal book. Further you need to refer ICAI Practice Manuals, RTP and MTP's (can be downloaded frm icai site) to score good marks. Prefer to write answers in a bullet-wise manner and to the point.

You can refer my NOTES on AUDITING on my blog www.castudyarena.com. I have uploaded 8 notes so far and in the process of uploading further.

I agree with Krishna's advice with the resources that he has mentioned. Now, the important thing to understand in an Audit paper is to write quality answer than quantity of pages that you may have written at degree level.
