The ACA Audit and Assurance exam is typically taken alongside the highly technical Financial Accounting and Reporting exam which can cause candidates issues when it comes to finding an appropriate balance. The pass rate for this exam was 87.7% in the most recent exam season which demonstrates that this exam is passable provided students put in the necessary question practice.

To pass the ICAEW ACA Audit and Assurance exam, candidates should focus on question practice and getting to grips with the permitted texts. Within the exam, the key priorities should be writing as much as possible for each question whilst being efficient and sticking to pre-determined timings.

During my time taking the ACA exams, I took Audit and Assurance alongside both Tax Compliance and Financial Accounting and Reporting. As Audit and Assurance was by far the least technically challenging of the three, I ended up spending much more revision time on the others. In order to be successful, I had to make sure my Audit and Assurance studying was as efficient as possible.

With that in mind, I have created the below guide which should help anyone studying for the Audit and Assurance exam to organise a revision and exam strategy and ultimately pass this exam.

How to pass the ACA Audit and Assurance exam

Passing the ACA Audit and Assurance exam will come down to doing a few key things well. Firstly – how well the candidate prepares via question bank practice and preparation of the permitted texts and secondly how well the candidate is able to perform on exam day.

Whilst both are as important as each other, performing well on exam day is the easier part. This will simply be a case of managing exam nerves (which should be much easier to do by this stage of the ACA qualification), managing the fatigue of taking a long exam (often on the same day as another professional level exam) and finally getting enough sleep leading up to the exam to be able to perform on exam day.

The difficult part is learning, revising and mastering the content. For most students this will involve actively engaging with the tuition and practising questions repetitively. There is no silver bullet here – it’s simply a case of putting the work in and sticking to a smart plan.

Success in the preparation phase will come down to the below points:

  • Listening intently to the tutor and actively engaging with exercises and questions. Speak up if you don’t understand a concept or method.
  • Creating a realistic but thorough revision timetable that you can stick to and that will provide enough study hours to master the content whilst also leaving some time to relax.
  • Pummeling the question bank and mock exams repeatedly and learning from mistakes when you make them.
  • Devise a smart strategy for exam day.

You only need 55% to pass and this fact should be your best friend when it comes to this exam. If you manage to practice questions repetitively, get to grips with the permitted texts and new data analytics software, calculate and stick to preset timings and write as much as you can for each question, you’ll be in a great position to pass this exam.

How the ACA Audit and Assurance exam is structured

The ACA Audit and Assurance exam falls within the professional level as shown below.

ACA Audit and Assurance exam

The exam is made up of 6 short-form questions which are typically worth 2-4 marks per question and 3 long-form questions which vary from 20-40 marks per question.

The single most important thing you can do on this exam is to get your timings right and spend the correct amount of time on each question and sub-question. To do this effectively, you’ll need to calculate the correct amount of time to spend on each question (process shown below) and be highly disciplined in sticking to these timings. Even if you’re halfway through a sentence when your time for the question is up, move on!

So what’s the most efficient way of working out the time you should spent per question?

Step 1 – write down how long the exam is in minutes. We know the exam is two and a half hour long. This converts to 150 minutes in total.

Step 2 – Take off 10 minutes from the total which is the time set aside to work out and write down your timings per question. This leaves 140 minutes of actual question-answering time.

Step 3 – We now know we have 140 minutes to answer questions worth 100 marks. This is 1.4 minutes (1 minute 24 seconds) per question.

Step 4 – Go through the exam script and for each question or sub-question, calculate the time per question. For example, if a question is worth 15 marks, you would give yourself 15 * 1.4 minutes = 21 minutes.

Step 5 – Once you have done this for each question, confirm the timings for each question sums up to 140 minutes in total so you know you haven’t gone wrong anywhere.

This may sound like a hassle but with practice you can do all of this for an exam script in under five minutes.

Taking the time to do this and then being strict with yourself to stick to the timings is the single most effective thing you can do. This simple technique will make sure you apply a reasonable amount of time to each question and don’t fall victim to running out of time which is the reason many candidates fail this exam.

This is an important point – if any single question is taking you longer than the calculated time, move on! The single biggest reason people will fail this exam (other than not understanding the content) – is time management.

If you believe you have completed your answer to a particular question within the predetermined time, feel free to move onto the next one. You have just saved yourself a few minutes which can be put towards any question you have more to write for at the end.

The syllabus will cover:

  1. Legal and other professional regulations, ethics, accepting and managing engagements and current issues (35%).
  2. Planning and performing engagements (40%).
  3. Concluding and reporting on engagements (25%).

ACA Audit and Assurance exam – revision strategy

With the exception of self-taught students, most of your revision time will be determined by your tuition provider.

For the Audit and Assurance exam, revision or practice outside of the classroom should focus on the following items; question bank questions, mock exams, reviewing particular topics within the course notes and updating/reviewing your mistake notepad as outlined below.

Many students will take the Audit and Assurance exam alongside the tricky Financial Accounting and Reporting (FAR) exam. Whilst this will vary by student, my advice is to spend 75% of total revision time on FAR due to the increased complexity and volume of content.

This leaves 25% of revision time for Audit and Assurance which means every hour spent needs to be efficient as possible.

In terms of how revision should be structured, my advice would be to complete a full long question or a group of short-form questions, mark them and then note down improvements that could be made.

When studying, implement the pomodoro technique (which is explained briefly in this Youtube video). This will maximise your productivity and help to avoid burnout and concentration lapses.

If it suits your studying style, consider joining a study group with one or two other students. I found this immensely helpful, not only does it help keep you accountable to study in line with your revision timetable, you and your study group can help cover each other’s weaknesses.

Beyond the above points, the most important thing is to listen and implement the advice of your tutors. They have likely taught this exam module several times and are well placed to advise on the best ways to revise and practice.

ACA Audit and Assurance open-book and permitted text tips

Unlike the certificate level exams, the Audit and Assurance exam allows students to bring in ‘permitted texts’ as laid out on the ICAEW website. This is slightly different from a full open-book exam which allows candidates to bring in any resources they like as the permitted texts are limited to certain publications.

During the exam, the permitted texts are PDF’s accessible by a link within the online software. The only exception is the IFRS blue book which can be taken into the exam in physical form.

These permitted texts include publications such as ethical standards and international auditing standards. Whilst these permitted texts do, in theory, contain a lot of the answers needed to adequately answer the questions, many candidates report that the online resources are cumbersome to use and difficult to navigate through which can mean they are time-consuming to use.

Due to this, my advice would be to get to grips with the permitted texts and understand how to best use them but don’t rely on them. For this exam, the permitted texts should be limited to last resort territory either when you simply have no idea on what to put for a question or at the end of the exam if you have some time to flesh out your earlier answers.

How to learn from your mistakes effectively

To make the most of your revision sessions, you need to be diligent in learning from your mistakes and making sure you don’t make the same errors repeatedly.

I’ve found using the ‘notepad method‘ particularly effective for this.

Here’s how it works – buy a nice new notepad and write ‘ACA Audit and Assurance exam – mistakes’ on the front cover. Any time you make an error in mock exams, the question bank or the end of chapter questions within the course notes, write a note in your notepad explaining what the error was, why you made it, what the correct answer should be and a reminder to yourself about how this error can be avoided in the future.

At the start of each revision session, read through this notepad of mistakes and you’ll gradually stop making the same errors as you become more conscious of them.

ACA Audit and Assurance exam – timings and strategy

As well as having a revision strategy, candidates should think about implementing a specific exam strategy to maximize their chances of success. This strategy should be based on three core factors: writing as much as possible for each question, being careful not to take too much time on any single question and ‘playing the game’ to get over 55%.

In this exam, there seems to be a correlation between the amount written and the exam score. As this exam is positively marked, i.e. you don’t get points taken away for wrong answers, it makes sense to write as much as possible for each question whilst avoiding going over the allotted time on any given qustion. This doesn’t mean writing whatever and hoping for the best but rather being precise and getting down as many sentences as possible which have a chance of earning you marks.

On a related note, the ICAEW has confirmed for the most recent exam sitting that bullet-point answers are fine for the short questions. My advice to candidates is to make the most of this. Bullet points allow candidates to get down points much faster which allows them to give more answers and stand a better chance of winning marks.

As discussed earlier, the key to success in this exam is being diligent with timings. For each question, multiply the number of marks by 1.4 minutes to calculate the total time to answer the question and then stick to this time.

By doing this, candidates will make sure they spend sufficient time answering each question. This is linked to the third factor which is that the pass-mark is only 55%. By leaving sufficient time for each question, candidates are able to have a good stab at every part of the exam which makes achieving the 55% pass mark much easier.

How to use the ACA data analytics software

From March 2021, the ICAEW has begun to add data analytics software to the Audit and Assurance exam. The idea behind this is to prepare students for audit work which increasingly relies on technology to analyse and present client’s financial data.

Within the exam, certain data analytics modules are tested which tends to involve reviewing charts and tables based on a fictional clients financial information and answering questions on the information presented.

This can crop up in any of the questions within the Audit and Assurance exam and typically makes up 10-12 marks in total. The most common type of question asked in relation to the data analytics software is a ‘responding to risk’ style question whereby candidates identify a specific risk from the data presented and layout possible procedural responses to that risk.

How to tackle concepts you keep getting wrong

As with any exam, a certain proportion of the content will be challenging. It may even feel at times like you can’t understand a particular item no matter how much you read the course notes and practice questions.

If you find yourself in this situation and are beginning to get overwhelmed, here are my suggestions:

  1. Consider ignoring it. This will only work if it’s not a central concept. This may sound counter-intuitive but if for example, you are really struggling in one area and just can’t seem to get it, it may not be the worst idea to forget it. Remember, you only need 55% to pass the exam and this area is unlikely to make up more than 5% of the total points. Does it not, therefore, make sense to avoid spending hours trying to understand this concept when that time could be spent on more useful revision?
  2. If the topic can’t be ignored – ask either your tutor or a classmate who does understand it for help. In my experience, both tutors and classmates are more than willing to explain a concept and sometimes a new perspective can help you understand something that was previously incomprehensible.
  3. Consider google-ing the topic. A lot of very specific questions are explained online on blogs, forums or Youtube videos which may help unlock your understanding.

Tips for exam day

I often use the metaphor of a boxer preparing for a fight for how candidates should prepare for the ACA exams. Both the pre-fight preparation and the fight-day itself are equally important. If you don’t prepare properly, you won’t be successful. Similarly, if you prepare well, but perform poorly on the day, you won’t be successful.

With this in mind, I’ve laid out a few tips to help optimise your exam day performance that worked consistently for me during my exam days.

Needless to say, being well prepared is crucial. It doesn’t matter how well you sleep the night before the exam or how dialled in your pre-exam ritual is if you don’t know the content. There is nothing that will help calm exam nerves to the extent that being over-prepared will.

As well as being well prepared on the exam content, it also pays off to be well prepared practically speaking. Things go wrong in exams so have contingencies planned. If you’re doing your exam from home as many are at the moment, have a backup plan if your wifi cuts out e.g. a mobile phone hotspot connection. Take an earlier train into the exam centre in case there are signal failures (which there seem to be most days).

My next tip may sound a bit like something your Grandmother would say but regardless – get a good night’s sleep for the week leading up to the exam. One good sleep does not make up for poor sleep every other night. Get your 7-8 hours per night. Believe me, this will have a bigger impact than another hour of revision late at night. The research is very clear that good sleep is crucial for memory retention which is a big part of all of the ACA exams.

Finally, a quick point on when is the right time to stop revising. My advice is to stop revising a few hours before you sleep on the night before the exam and relax for a few hours. Trying to cram material late on the night before the exam will probably not help and almost certainly make it more difficult to sleep.

Should you take your ACA exam exemption?

Some students will be exempt from certain exams due to the credit for prior learning (CPL) system. For students who have studied Accounting at university or have done similar qualifications in the past, certain ICAEW ACA modules will be a duplication of content. Rather than repeating an exam already passed, students can apply for a credit for prior learning and become exempt from the exam.

More information on ACA exam exemptions can be found here.

Whether students apply for and take exam exemptions is up to them but it’s worth noting the below advantage and disadvantage of doing so.

The big advantage is clear – students can save themselves significant study time and exam stress by taking an exemption and use that saved time for other exams they are not exempt from taking.

However, the disadvantage is that the ACA qualification is structured in tiers as discussed above. For example, students will take ‘Accounting’ at the certificate level, ‘Financial, Accounting and Reporting’ at the professional level and ‘Corporate Reporting’ at the advanced level with the knowledge and skills being built upon and compounded throughout.

This means if a student were to take an exemption from the Accounting exam for example – when it comes to taking the difficult Financial Accounting and Reporting exam, the underlying content will not be fresh in mind which may become a difficult obstacle to overcome.
