Pankaj garg main book (not sure abt scanner) is gud along with icai pm. I failed for 3 times in 1st grp becoz of audit. But this time studied from pankaj garg n pm n cleared the grp.
You should read Pankaj Garg sir book first and focus on professional ethics topic(16 marks).Try to read PM for SA.First secure 40-45 marks in audit and then prepare for exemption.
