Auditing and Attestation (AUD) is one of the four parts of the Uniform CPA exam. All states and jurisdictions require students to pass each of the four sections with at least 75% within an 18-month time period, regardless of the other state-specific licensing requirements. Failing to do so will result in the exam parts passed outside of the 18-month window to expire, and the examinee will need to retake that section or sections. Therefore, it is best to go in as prepared as possible, and to give yourself enough time in which to complete them while factoring in the possibility of failing one or more sections.

AUD exam study tips

Choosing the right approach for studying any subject is subjective, because everyone has their own approach that work best for them. Generally, there are two main aspects to studying for the CPA exam, though. These are covering the course material through study guides and pounding Multiple Choice Questions (MCQs.) Most CPAs who have passed the AUD section recommend running through as many MCQ sets as you can before the exam, preferably running through a set multiple times until you feel that you understand the content through reviewing the information on the sections you struggled with, and secondly until you get 90-100% for that set. Of course, it is usually better to take the MCQ set, review and then wait a day or two before trying again, so that you don’t just answer by rote. This technique is helpful in identifying the topics that you are weak in, as well as familiarizing you with the type of questions that should come up in the exam. Fortunately, there are many free MCQ sets available online, and they also usually come part of online study packages.

As for revision, it is best to use texts that have a strong reputation, such as those by Wiley and Becker. If you can’t afford them, you can try the secondhand market or try to borrow them from a public library. There are many other study resources   besides these, such as the study plans, premade revision cards and videos, like those of Farhat’s Accounting Lectures and Edspira. Some of them are even free. Although just going through the material is helpful, a good way to really internalize it is to summarize the notes as you go along and make to also make index cards of the important definition or topics with which to revise later. Reading through the notes and cards as soon as you are done compiling them, will help you to absorb the information even more, if you have time. Another benefit to summarizing your work, is that it forces you to engage with the text and to actually consider what it is saying and that you truly understand the concepts. Additionally, it is a good idea to set a manageable study schedule for yourself with breaks and rewards to recharge yourself with. Breaks are especially important if you are faced with a section that you cannot understand, as sometimes stepping back can calm you and give your subconscious a moment to process it.

However, the AIS-CPA recommends setting aside between 70-90 hours of study time towards the exam. Therefore, studying for around 2 hours a day for between 6-7 weeks, should be enough preparation time. You could also reduce that to 3-4 weeks by studying 3-4 hours a day.

How difficult is the AUD exam?

With a pass rate that is only slightly better than the FAR exam section, AUD is considered one of the hardest sections of the CPA exam. It should be easier for those applicants who chose to fulfill their experience requirements in an auditing firm or department of a company. It is due to this that CPA examinees usually take these two sections first, so as to lessen there chances of missing the 18-month window in which they need to pass all for sections of the exam.
