CPA Exam is considered one of the most demanding professional credentialing tests in accounting. Here we discuss factors that contribute to the complexity of the CPA Exam along with some expert tips to pass. Besides other factors, how hard you may find the exam primarily depends on your preparedness and approach to the exam. 

How Hard is CPA Exam

Passing the CPA exam is one of the prerequisites to attain a CPA license. The following entities are involved in administering the exam:

  • American Institute of Certified Public Accountants (AICPA)
  • 55 US State Boards of Accountancy. 
  • National Association of State Boards of Accountancy (NASBA)
  • Prometric

To understand the level of difficulty of the CPA exam, you should be aware of its scope, format, timing, testing, and grading process. The knowledge of these helps you channelize your efforts in the right direction. Also, it gives you an idea about the level of preparation required of you.

Let’s start with understanding the various aspects of the exam and its influence on its perceived difficulty.

What makes the CPA Exam Hard?

The key factor that influences our opinion about the difficulty of any exam is our level of preparation. Besides that, the main factors that make it so hard are discussed below.


The exam tests the expertise of aspiring CPAs in the following four sections: Business Environment & Concepts (BEC), Regulation (REG), Financial Accounting & Reporting (FAR), and Auditing & Attestation (AUD).

Each of these sections has to be taken separately. Each section contains five testlets to be finished in four hours. Moreover, you have to take all the testlets consecutively with only 15 minutes break (after the third testlet). Hence, this format requires you to prepare yourself physically and mentally to be focused for a long time.

With a large number of questions and not enough time for each, the exam also requires you to practice thinking on your feet. Moreover, there are a fixed number of questions in each testlet and no option to review a testlet once submitted. This exerts extra pressure to answer all questions in a testlet correctly before submitting.

Type of questions

There are three types of questions asked in the CPA exam:

  • Multiple-choice questions (MCQs) – Two testlets
  • Task-based simulations (TBSs) – Three testlets (two for BEC)
  • Written communication tasks (WCTs) – One testlet (for BEC)

You get the MCQ testlets first, then TBS and finally, the WCT (only for BEC). MCQs present multiple answer options, while TBSs give out real-life case studies. On the other hand, WCTs tests your writing ability. With a variety of questions, it is challenging to adapt to and time them to ensure you complete the test on time.

Though MCQs provide answer options, the tricky part is that there may be more than one correct answer to a question. So, you have to use your judgement to come up with the right as well as the best possible response. Generally, TBSs are considered to be the most challenging. This is because they expose you to the real-life workplace scenarios and test your ability in dealing with them.

Furthermore, each testlet has a fixed number of operational and pretest questions. The operational questions add to your final score, while the pretest questions don’t. However, there is no way of distinguishing between them. So, there is a possibility of wasting a lot of time on tricky pretest questions, which do not count on your final score.

Scope of information tested

The extent of information covered in each of the sections is exhaustive. Each section covers numerous topics in various accounting and business areas. The AICPA’s Exam Blueprints gives a detailed account of topics covered in each section.

Besides, each section has several representative tasks that you must be able to perform as a CPA. There are around 570 representative tasks listed in the Blueprints. You must make an effort to go through each task to ensure you have covered everything from a topic.

Apart from the exhaustive syllabus, the AICPA also keeps changing the curriculum every few years. This is to ensure that the exam reflects the changes happening to the accounting profession. So, the exam requires you to keep yourself abreast of all recent reforms to taxation and other laws.

What makes this exam difficult is the extensive coverage of various topics in such a short period. However, if you take the time to understand and learn the exam content thoroughly, your performance will undoubtedly improve.

Skills tested on the exam

The exam tests you on four levels: remembering and understanding, application, analysis and evaluation. It assesses your higher-order thinking skills. This is to ensure that you use your judgement and problem-solving abilities to real-life situations.  

With the exam testing a great deal of information at various skill levels, passing the exam may be quite demanding. The purpose of the CPA exam is to assure that you are competent enough to handle any business situation as a CPA. And also uphold the public interest and ethics of the profession.

Though difficult, this rigorous training will help you expand your thinking and reasoning horizons. Also, it will condition your mind to come up with novel solutions to challenging problems. 

Scoring and testing process

You must score at least 75 points (0-99) in each of the four CPA exam sections within 18 months to qualify. The AICPA arrives at the final score by calculating the weighted sum of scaled scores of all testlets (MCQ, TBS, and WCT). Each question is scaled based on correctness, difficulty level, and statistical characteristics.

The AICPA also uses a multi-stage adaptive testing model for the MCQ testlets. Under this, the test proceeds depending on your performance. With better performance, you get difficult testlets which have questions worth more points. This unique testing and scoring process renders the exam more difficult to comprehend.

Timing of the exam

You must pass all four exam sections within the 18 months, starting from the time you pass the first exam. Or else, you will lose the credit of the passed sections. This adds to the perceived difficulty of the exam.

However, the introduction of the continuous testing model has come as a relief to the candidates. It permits them to take the exam throughout the year without waiting for testing windows.  

Furthermore, there is no definite order to sit for the exam sections. However, choosing a suitable order definitely helps in preparing and taking different exam sections with ease. But deciding on an appropriate sequence is another tough call.

Education background and work experience

How difficult you find the exams also depends a lot on your educational background, prior exposure to relevant subjects, and work experience in specific areas.

Candidates with prior experience in taxation may find the REG section easy, while others may find it difficult. However, FAR with its extensive coverage of accounting frameworks, may appear easy for those working in the relevant field.

AUD may seem difficult to students but easy to candidates with auditing experience. Moreover, students with business coursework may find BEC easy. Hence, prior knowledge about a subject or related work experience may contribute to your opinion on how hard you find the exam.

CPA Pass Rates

To comprehend the difficulty of the exam, let’s look at CPA exam pass rates. The pass rates reveal the performance of candidates in the exams over the years. Therefore, they vary from year to year. AICPA releases the pass rates for each exam section every quarter.

The average pass rate is 50% for each exam section. The low pass rates of an exam are usually an indicator of its difficulty. However, as per AICPA, the pass rates reflect the level of preparation of candidates in a particular year compared to previous years. It has nothing to do with the exam being more easy or difficult in a specific year.

A mid-way pass rate seems discouraging to most aspiring candidates. However, don’t let it define your chances of success. Remember that your perseverance and effort solely determine your success.

However, you can scan through the pass rates to understand the general trend. Here are the currently released pass rates for Q1 and Q2 2021.

  • As soon as you submit the application form, start planning out your exam schedule. 
  • Once you receive the NTS, book your first exam right away. 
  • Go through CPA Blueprints before scheduling. 
  • Take up the most challenging section first to let the burden off your shoulders, or the easiest one to start with a light mindset. 
  • Don’t leave too much time between the sections (take 1-2 weeks breather).

Here are two recommended sequences to take the sections:


Please note that AUD and FAR have overlapping content, so it is advisable to schedule them close to each other. Also, you must retake a failed section as soon as possible. This will ensure you do not forget the subject.  

However, there is no perfect schedule. So, choose the one that suits your circumstances.

Preparation time

The time taken by candidates to clear the exam successfully depends on their individual strengths and weaknesses. Also, it may vary as per a candidate’s educational background, work experience, exposure to the subjects, and the relevant skills possessed. 

As per AICPA, the study schedule of candidates can range from a few hours to 25 hours a week. On average, it takes 10-14 months for a candidate to pass the licensure test successfully.  The following table presents an approximate timeline for preparation.
