How Hard is the CPA Exam? Pass Rates, Sections, & Study Time

Is the CPA Exam Difficult? The Unfiltered Truth You Need to Know

The Direct Answer: How Hard is the CPA Exam, Really?

The Uniform Certified Public Accountant (CPA) Examination is, objectively, one of the most challenging professional credentialing tests in the world. It is a grueling four-part examination covering a vast body of knowledge in accounting, audit, tax, and IT. According to historical data from the American Institute of CPAs (AICPA) and the National Association of State Boards of Accountancy (NASBA), the overall cumulative pass rate for all sections of the exam typically hovers just under 50%. This means that, on average, for every two candidates who attempt a section, only one will pass. This low pass rate is a clear, data-driven indicator of its difficulty. Adding to the pressure, a candidate must achieve a minimum scaled score of 75 on all four sections within a rolling 30-month window from the time they pass their first section. This time constraint—not just the content—is what separates the successful candidates from those who fail to earn their CPA license.

Decoding CPA Exam Difficulty: Key Statistics and Pass Rates by Section

2024/2025 CPA Exam Pass Rate Breakdown: Which Sections are Toughest?

The most objective measure of how hard the CPA Exam is comes directly from the candidate performance data released by the American Institute of Certified Public Accountants (AICPA). Historically, and continuing under the new 2024 CPA Evolution structure, the pass rates clearly define the most challenging sections.

Financial Accounting and Reporting (FAR) is consistently considered the most difficult core section. Since the 2024 changes, FAR’s cumulative pass rates have consistently been the lowest of the core exams, hovering around the 40% mark. This difficulty is attributed to the sheer volume of U.S. GAAP principles, IFRS, and the technical complexity of topics like governmental and non-profit accounting. While some content was moved to the new discipline section, Business Analysis and Reporting (BAR), FAR remains an immense challenge. In fact, BAR itself has also seen low initial cumulative pass rates, often below 45%, absorbing much of the highly analytical and difficult financial reporting material.

In contrast, Regulation (REG) typically sees much higher pass rates, frequently landing above 60%. This section requires intense memorization and application of complex federal tax law, ethics, and business law. Candidates often find the tax computation topics more straightforward and structured than the conceptual nature of accounting and auditing, which contributes to the higher success rate. The new discipline, Tax Compliance and Planning (TCP), has shown the highest pass rates of all sections, often exceeding 75%, confirming that a specialization in tax offers a high probability of success for those with a strong tax foundation.

CPA Exam Section	2024 Cumulative Pass Rate (Approx.)	2023 Cumulative Pass Rate (Approx.)	Type of Challenge
FAR (Financial Accounting & Reporting)	39.59%	42.12%	Volume, Technical Complexity, IFRS/GAAP
AUD (Auditing & Attestation)	45.79%	46.75%	Conceptual Application, Judgment, Wording
REG (Regulation)	62.61%	57.82%	Tax Law Memorization, Detailed Application
BAR (Business Analysis & Reporting)	38.08%	N/A (New)	Advanced Financial Accounting & Reporting
ISC (Information Systems & Controls)	58.00%	N/A (New)	Technical IT and Systems Assurance
TCP (Tax Compliance & Planning)	73.91%	N/A (New)	Tax Planning and Advanced Compliance

Data compiled from AICPA-reported cumulative pass rates for the specified calendar years.

The definitive data in the table above provides transparent evidence for your study plan, confirming that while FAR and the new BAR discipline are statistically the toughest hurdles, REG and TCP are the sections where candidates have the highest statistical probability of passing.

The 30-Month Clock: The Time Constraint that Adds Pressure

Beyond the difficulty of the content itself, a critical factor that amplifies the challenge of the CPA Exam is the 30-month rule. Once you pass your first section, you have a rolling 30-month period to pass the remaining three sections.

This deadline transforms the individual section difficulty into a strategic and psychological test of endurance. A 40% section pass rate, while tough, becomes significantly more daunting when you know that failing means not only having to retake that expensive and time-consuming section but also having the 30-month clock continue to tick away on your previously passed sections. Many candidates find the need to constantly monitor the risk of an already passed section expiring to be a major source of stress. Effective time management and disciplined adherence to a study schedule are essential to ensure you complete all four parts well within this statutory window.

The Scope Challenge: Why the CPA is a Test of Endurance, Not Just Knowledge

The true measure of the CPA Exam’s difficulty is not just the complexity of individual topics, but the sheer volume of material a candidate must master across all four sections. This extensive scope transforms the process into a demanding test of endurance and time management, requiring a significant commitment far beyond that of a typical college final. For the average candidate, the full examination—comprising three Core sections and one Discipline section—demands between 300 and 500 total study hours, with many successful candidates reporting spending even more. Each of the four-hour exams is a marathon of highly specialized concepts, making disciplined, long-term focus the most critical factor for success.

Vast Content vs. Deep Application: The Dual Study Requirement

To pass the CPA Exam, candidates face a dual study requirement: grasping a massive body of content and developing the ability to apply that knowledge at a professional level. The examination’s governing body, the AICPA, explicitly outlines the required competencies in its CPA Exam Blueprints. These Blueprints emphasize higher-order skills such such as Analysis and Evaluation over simple recall, signifying that rote memorization is insufficient.

To effectively prepare for this application-heavy format, a candidate must demonstrate not just a passing familiarity with U.S. GAAP, auditing standards, or tax law, but a deep, functional understanding of how and when to apply these rules to complex, real-world scenarios. This necessary shift from academic knowledge to professional-level judgment is a primary reason why the exam requires hundreds of dedicated study hours.

Multiple Question Formats: Mastering MCQs and Task-Based Simulations (TBS)

The CPA Exam is broken down into two major question formats: Multiple-Choice Questions (MCQs) and Task-Based Simulations (TBSs). While MCQs test foundational knowledge and understanding, the Task-Based Simulations (TBSs) are overwhelmingly cited by candidates as the hardest question type and the biggest time sink.

Comprising 50% of the total score for most sections (40% for the ISC Discipline), TBSs are mini-case studies that mirror the complexity of a newly licensed CPA’s daily work. They require you to analyze extensive documentation, financial statements, and supporting exhibits, and then apply complex concepts to reach a solution.

The difficulty of TBSs stems from three main factors:

Complexity: They often integrate multiple content areas into a single scenario, demanding a holistic grasp of the subject.
Time Pressure: Sifting through numerous documents and exhibits under the four-hour time limit is a significant challenge.
Real-World Skills: These simulations often require the use of the authoritative literature (a digital version of the professional standards), testing a candidate’s ability to research and apply technical guidance efficiently—a core professional skill that goes beyond basic test-taking. Mastering this format requires a study plan focused on extensive, timed practice, ensuring that when the high-stakes moment arrives, the application of knowledge is second nature.

Which CPA Section is Hardest for You? A Personal Experience Perspective

The objective pass rates released by the AICPA offer a crucial baseline for difficulty, but the truth is that the hardest section on the CPA Exam is almost always the one that aligns least with your personal background and professional experience. Your prior knowledge and comfort level with a subject will profoundly impact your study time and the perceived difficulty. Success in passing this rigorous examination requires not only knowledge but also self-awareness regarding your specific subject matter strengths and weaknesses.

Why Accounting Majors Fear FAR and Auditors Struggle with AUD

While Financial Accounting and Reporting (FAR) is statistically the most difficult Core section by a narrow margin—frequently due to the sheer volume of material—many CPA candidates find their greatest challenge lies in Auditing and Attestation (AUD). Candidates with strong financial accounting backgrounds often feel overwhelmed by the subtle, judgmental language of AUD questions, a section that requires you to “think like an auditor” rather than crunching numbers. Conversely, candidates who have spent their careers in audit roles often find they can quickly grasp AUD’s concepts but struggle with the intricate U.S. GAAP calculations and specialized reporting requirements of FAR.

Candidates with a background heavily focused on tax, such as those working in private tax practice or specializing in a tax-heavy degree, often experience the opposite effect. They may find Regulation (REG)—a section demanding intense memorization and application of complex tax law—to be the most straightforward of the Core exams. This demonstrates that difficulty is highly subjective: a candidate’s established comfort in tax law transforms the rule-heavy REG section into a relative strength, while the same candidate might feel unprepared for the analysis and professional judgment required in AUD.

The Discipline Sections (BAR, ISC, TCP): New Difficulty Variables

The new Discipline sections—Business Analysis and Reporting (BAR), Information Systems and Controls (ISC), and Tax Compliance and Planning (TCP)—introduce a new layer of personalized difficulty that depends entirely on a candidate’s chosen specialization.

Tax Compliance and Planning (TCP) is the most appealing choice for many tax professionals. This specialization focuses on advanced taxation, building on the REG core material. Statistically, TCP has been the highest-performing section across all CPA exams, boasting pass rates over 75% in recent quarters, as reported by review providers who compile this data. This high success rate is largely attributed to the candidate self-selection bias: those who choose TCP already have a deep affinity for and experience in tax.
Business Analysis and Reporting (BAR), which focuses on advanced financial reporting and management accounting, currently presents the lowest pass rate of the three disciplines, often falling below 40%. This difficulty is due to its advanced treatment of complex FAR topics, particularly governmental accounting.
Information Systems and Controls (ISC) sits in the middle, generally proving more manageable than BAR but more challenging than TCP.

Understanding this dynamic is essential for a strategic study plan: do not rely solely on the overall average pass rate. Use your academic history and professional experience as a guide, and consider this insight from a survey of over 4,600 CPA candidates aggregated by a major review course: while BAR was statistically the lowest in pass rate, FAR was overwhelmingly chosen as the most difficult by 63% of respondents, with AUD in a distant second place at 24%. This community consensus highlights that perceived difficulty often centers on the sheer volume and stress of the Core sections, regardless of your ultimate discipline choice.

A Proven 5-Step Strategy to Conquer the CPA Exam’s Difficulty

The difficulty of the “how hard is the CPA exam” question is best answered not by reciting statistics, but by detailing a bulletproof strategy that turns overwhelming content into manageable milestones. Successfully navigating the four 4-hour exams is a marathon that requires a tactical study approach and unwavering discipline. For nearly all candidates, a structured study plan allocating 100-150 hours per section is a non-negotiable requirement for success, totaling an average of 400 to 600 hours for the full examination.

Step 1: Front-load the Hardest Section (FAR) to Build Momentum

The path to passing the exam starts with choosing the right section order. We strongly recommend candidates begin with Financial Accounting and Reporting (FAR). Although it is the most voluminous and complex section—often intimidating candidates—passing it first accomplishes three critical goals:

Establishes Confidence: Conquering the most challenging section first provides a psychological boost and a strong foundation for the remaining exams.
Maximizes Retention: Much of the technical accounting knowledge covered in FAR, particularly governmental and not-for-profit accounting, is not highly relevant to daily work for many candidates, making it easily forgotten. Tackling it first maximizes the chance of retaining it for the 30-month testing window.
Content Overlap: FAR concepts lay the groundwork for understanding topics in the Auditing and Attestation (AUD) and Business Analysis and Reporting (BAR) sections, creating efficiencies in your subsequent study efforts.

Step 2: Time Management Mastery: Allocating Study Hours Effectively

The total hours invested are less important than the quality and consistency of the time spent. Experts agree that two to three hours per weekday, combined with longer weekend sessions, strikes the ideal balance for a working professional.

The most successful CPA candidates do not just passively re-read material; they leverage an Active Recall and Spaced Repetition study loop. This technique, proven by cognitive science to significantly increase memory retention, involves:

Active Recall: Immediately after studying a topic, you force your brain to retrieve the information without consulting notes (e.g., solving practice questions or explaining the concept out loud).
Spaced Repetition: You revisit previously learned material at increasing intervals (e.g., a review session one day later, then three days, then a week). This intentional spacing ensures knowledge moves from short-term to long-term memory. This proprietary study method is central to many successful review courses and is associated with candidates consistently achieving higher scores on practice tests.

Step 3: The Power of Repetition and High-Fidelity Practice Exams

Passing the CPA exam is as much a test of endurance and time management as it is a test of knowledge. This is why high-fidelity mock exams are non-negotiable.

Successful candidates use two to three full-length mock exams to simulate the exact 4-hour time constraint of the actual test. This practice is crucial for:

Pacing and Fatigue Management: It trains you to maintain focus and stamina for the full duration, a key factor in avoiding mental exhaustion and poor performance in the final testlets.
Mastering Task-Based Simulations (TBS): TBSs can account for up to 50% of your section score and are the most common reason candidates run out of time. Practicing the full 4-hour mock exam ensures you allocate sufficient time—typically 15-20 minutes per simulation—and develop the skill to apply knowledge in complex, real-world scenarios, a higher-order skill the AICPA heavily emphasizes.

By meticulously tracking their mock exam performance and focusing their review on areas where they consistently score below the passing threshold, candidates demonstrate the subject authority and strategic readiness required for the CPA credential.

Your Top Questions About CPA Exam Difficulty Answered

The journey to becoming a Certified Public Accountant is rigorous, and it is natural for candidates to benchmark the experience against other highly respected credentials. Below, we address the most common questions about the intensity and statistics of the exam process.

Q1. Is the CPA Exam Harder than the Bar Exam or CFA?

While difficulty is subjective and depends heavily on an individual’s background, many professionals who have tackled both the CPA Exam and the Bar Exam report the CPA Exam’s content to be more difficult due to the wider, more diverse scope of material. The CPA Exam is a marathon of four distinct sections, requiring rote memorization and deep application across financial accounting, auditing, and complex tax law within a tight 30-month window. The Bar Exam is an intensive two-day sprint, but the CPA’s four-part structure and the application of technical accounting standards are often cited as the greater endurance test.

In a comparison with the Chartered Financial Analyst (CFA) program, which involves three levels, the consensus among finance professionals is that the CFA is generally harder overall. The CFA program typically requires significantly more total study hours—often $900$ to $1,200$ hours across three levels, compared to the CPA’s recommended $300$ to $500$ hours for all four sections. The CFA’s overall cumulative pass rate for all three levels is also notably lower than the CPA’s. Our experience working with successful candidates suggests that the financial reporting sections of both exams share similar depth, but the sheer breadth and cumulative knowledge requirement of the CFA’s multi-level structure make it the more challenging credential to fully attain.

Q2. How Many Times Does the Average Person Take the CPA Exam?

It is common and, frankly, expected to fail at least one section of the CPA Exam. Given that the overall pass rates for individual sections consistently hover around $50%$, it is a statistical reality that a candidate will likely need multiple attempts to achieve a passing score of $75$ on all four parts. Official data and candidate surveys indicate that successful candidates take an average of $1.5$ to $2$ attempts per section to complete the entire exam sequence.

This is a critical insight for managing your expectations: you are not an outlier if you fail a section. The path to licensure is typically one of perseverance and retakes. A key factor in establishing success is leveraging a high-quality review course that provides a personalized, data-driven study plan and mock exams that truly replicate the pressure of the real test, allowing you to maximize your $1.5$ attempts efficiently.

Q3. What is the Hardest CPA Exam Section to Pass on the First Try?

Based on historical AICPA-reported cumulative pass rates, the sections with the lowest statistical success rates are the hardest to pass on the first attempt. Historically, Financial Accounting and Reporting (FAR) has maintained the lowest pass rate, often falling into the $39%$ to $45%$ range. Its difficulty stems from the massive volume of material and the technical depth required to master concepts from financial statements to governmental accounting.

With the launch of the CPA Evolution model, Business Analysis and Reporting (BAR), one of the new discipline sections, is statistically challenging. Data from the first year of the new exam structure shows BAR pass rates also frequently dipping into the $35%$ to $43%$ range. This confirms that sections focused on complex financial reporting and analysis continue to be the biggest statistical hurdle for candidates. Conversely, the Tax Compliance and Planning (TCP) discipline has shown the highest pass rates, frequently exceeding $70%$, which suggests that a targeted focus on tax can be a strategic choice for your specialization.

Final Takeaways: Mastering Your Journey to a CPA License in 2025

Your 3 Key Actionable Steps to Beat the Difficulty Curve

The CPA Exam is undeniably challenging—its overall pass rate historically hovers around 50%, with sections like Financial Accounting and Reporting (FAR) and Business Analysis and Reporting (BAR) often dipping into the low 40s according to recent AICPA data. However, this high barrier to entry is precisely what makes the CPA license a badge of honor and ensures its enduring professional value. The most successful strategy for passing is a combination of relentless, focused time management and the use of high-quality, up-to-date study materials. Here are the three non-negotiable steps to master the exam’s difficulty:

1. Embrace the Structured Plan: Treat your study schedule as a non-negotiable second job, allocating a minimum of 100-150 hours per section. Based on the expertise of leading review course providers, this dedicated time is crucial. We know, for example, that candidates who meet structured study targets often achieve pass rates significantly higher than the national average, underscoring the value of a formalized, time-bound approach.
2. Prioritize Application Over Rote Recall: The new CPA Evolution exam structure emphasizes higher-order cognitive skills like analysis and evaluation, moving past simple memorization. Use your review course’s Task-Based Simulations (TBSs) extensively. This allows you to apply knowledge in complex, real-world scenarios, which is the only way to build the practical judgment necessary to score a 75 or higher.
3. Leverage High-Fidelity Practice: Ensure your study materials are current for the 2025 exam changes. The complexity of the material—especially in areas like complex financial reporting standards—demands materials that mirror the current AICPA Blueprints. Your practice environment should be a near-perfect simulation of the actual 4-hour exam to help manage fatigue and pacing, a common cause of failure.

What to Do Next

Your next step is to solidify your foundation and map out your entire testing window. Start by choosing a structured CPA review course—such as Becker, Gleim, or UWorld—that offers comprehensive materials and a proven track record of student success. Immediately follow that by planning your full 30-month testing schedule, deciding which core sections (AUD, FAR, REG) and which discipline (BAR, ISC, or TCP) you will tackle first. Do not delay this planning; maximizing the 30-month window from the moment you pass your first section is critical to your overall success.
