How to prepare audit by self study?

Hello,, my attempt is also in May 17. I'm studying from Padhuka.. It is the most comprehensive book for self study. (although it is very detailed). But never never go for Surbhi Bansal Audit book, she has consised the material so much that u won't be able to understand it by self study. If you've taken her class, then her book might be good, otherwise not. You'll have to cram audit if you study from her book. Believe me, Audit is not to be crammed. I wasted my money by purchasing her book first.
