This was my 4th Inter Group 2 attempt and again for the 4th time I failed in Audit paper scoring merely 33 Marks.I am studying from Tapan Jindal Book as I don't understand Surbhi Bansal book.Pl can anyone suggest as to what I should do and from which book to study so as to clear this time.
I desperately need to clear time as this is my last attempt and will have to switch to some other course if I don't clear Audit this time.
