i will not suggest you to go for G sekar for audit instead took a good book of any teacher and then prepare.
Here is my some personal tips for preparing audit.
HOW TO PREPARE AUDIT IN LESS TIME
how to prepare SAs
i will suggest you to that not to learn or cram all SAs as it would be very difficult for you as they cover approx 80 pages.
get compiler and point out which SAs are more important and get a reading of them very carefully.
after getting a reading try to make very short note of them to remember only their headings.
these short notes are called mnemonics .
a example of mnemonics is given by me on SA -315 is at the last of this page.
now in exam just write down the heading and use your own language for answer on the basis of the reading that you have taken .
but not try the simple language try to introduce those words in your language which are mostly used in audit by this you will show the examiner that you have enough understanding of SAs.
for example the word appropriate is mostly used rather than relevant.
Any further query is welcomed ...
Hope you will like my advice.
