Ca final audit

Dear Friends,

                      I want to know is their any amendments in the auditing subject in CA- Final. Because I have Surbhi Bansal Book for the May, 2017 attempt. So in this regard I want your advice whether I need to purchase a new book or I can read with the same book for the November, 2017 attempt.

And also if you have better choice for the book for CA Final auditing then please tell me because I am not able to score a good marks in auditing.

Thanks in Advance
