Tough subject - requires thourogh understanding of the basic auditing concepts to actually do well in the unit. Look up for materials through YouTube as there are tons of them that'll really bolster your knowledge. Markings are generally harsh and your answer should be relevant to the scenarios that are provided in the papers (hence memorizing the answers won't help you). However, with a proper study schedule, you'll pass this unit with a breeze.

Basic auditing concepts. Easy to get lost in the volume of content thrown at you. With a proper structure it is quite manageable.

A very interesting subject but very content heavy, make sure you keep up to date, the 3 hour seminars are boring but worthwhile
