This book has been updated in Sept 2020. As said by IIA, Audit skills and techniques are the focus. You need to have strong background in accounting. You also need to know how to act properly as an auditor. My suggestion is that you go through ALL TOPICS before taking any of the individual exam modules. Do NOT study on a per module basis. Instead, treat all of them as a whole - this will guarantee that you don't get tripped up when similar questions show up on different exam parts. And know the IPPF inside and out. Many correct answers come out from the IPPF International Professional Practices Framework.
