The US CPA is a licence, not just a certification, which shapes everything about how you approach it. Eligibility is governed by individual state boards, the exam tests applied judgement rather than recall, and a rolling credit window adds time pressure once you start. The exam follows the CPA Evolution model: three Core sections everyone takes, plus one Discipline section you choose. The goal of studying is to understand the accounting, auditing, and tax frameworks deeply enough to apply them in realistic task-based simulations, then to manage the four sections so the calendar never works against you. This guide is a full, self-study course: it walks through each section in depth, explains the concepts the questions are built on, and turns all of it into a section-by-section plan. It is original teaching material and study guidance only. It contains no real or simulated exam questions, and because tax law and state rules change, you should always confirm current rules against the AICPA’s CPA Exam Blueprints and your own state board before you book.
Chapter 1: Exam overview and how to use this guide
What the CPA actually measures
The CPA measures whether you are competent to practise public accounting in the United States: to prepare and report on financial information, to audit it, and to handle the tax and regulation that surround it. Because it is a licence to protect the public, the exam leans on applied judgement. Questions present a scenario and ask what the correct treatment is, what an auditor should do next, or how a transaction is taxed, rather than asking you to recite a rule in the abstract. That is why two formats run through every section: multiple-choice questions test breadth of knowledge, while task-based simulations test whether you can actually do the work, pulling figures into schedules, interpreting documents, and searching the authoritative literature.
The exam has four sections under CPA Evolution. The three Core sections are AUD (Auditing and Attestation), FAR (Financial Accounting and Reporting), and REG (Taxation and Regulation), and every candidate takes all three. The fourth is a single Discipline you choose from three options, letting you go deeper in the direction that fits your career. Each section is its own roughly four-hour exam, scored out of 99 with 75 the passing mark, and you pass them one at a time.
The licence, not just the exam
What makes the CPA different from most credentials is that passing the exam is necessary but not sufficient. You must also meet your state board’s education requirement, commonly 150 semester credit hours including specific accounting and business coursework, and an experience requirement, typically supervised work signed off by a licensed CPA. These rules vary by state, and they decide when you can even sit, so confirming them first is the single most important early step. The exam, the education, and the experience together produce the licence.
How to use this course
Read the section chapters (2 to 5) in whatever order matches your plan, but read Chapter 6 on the credit window before you book anything, because the timing strategy affects which section you sit first. Treat the bold terms and frameworks as a checklist: by the end of each section chapter you should be able to explain its core concepts and say how they show up in a simulation. The last three chapters turn the content into a schedule, a final-preparation routine, and a description of exam day. Worked illustrations appear where a concept is easy to misread, but none of these are exam questions. They are teaching examples that show how the idea behaves.
Chapter 2: Core - FAR (Financial Accounting and Reporting)
FAR is the broadest Core section and, for most candidates, the hardest, which is why many sit it first. It covers the preparation of financial statements and the accounting standards behind them, primarily US GAAP, across for-profit entities, not-for-profits, and state and local governments. If you can build and reason about financial statements, the rest of the exam has firmer ground to stand on.
What FAR covers and the framework behind it
At its heart FAR is about how transactions become financial statements. You study the conceptual framework, the elements of the statements (assets, liabilities, equity, revenue, expenses), and the specific standards that govern individual areas: revenue recognition, leases, income taxes, inventory, fixed assets, financial instruments, business combinations, and many more. The foundation everything rests on is accrual accounting, which records revenue when it is earned and expenses when they are incurred, regardless of when cash changes hands, in contrast to cash-basis accounting. Closely tied to it is the matching principle, the idea that expenses are recognised in the same period as the revenues they help generate. You also cover governmental and not-for-profit accounting, which use different reporting models and surprise candidates who expected only corporate GAAP.
Why it matters and a worked idea
FAR is the accounting bedrock that AUD audits and that parts of the Disciplines extend, so depth here pays off twice. The volume is the real challenge: the breadth of standards is large, and the simulations expect you to apply them, not just recognise them. As a teaching example of accrual reasoning: if a company receives cash in advance for a service it will deliver next year, accrual accounting records a liability (deferred revenue) now and recognises the revenue only as the service is performed, so cash received and revenue earned deliberately diverge, and a simulation that asks for the correct year-end balances is testing exactly that distinction. Build FAR study around understanding why each standard produces the entries it does, because memorising entries without the logic collapses under the exam’s applied questions.
Chapter 3: Core - AUD (Auditing and Attestation)
AUD covers the audit and attestation work that is the historic core of the CPA profession: examining financial information and reporting on whether it can be relied upon. It is conceptual and judgement-heavy rather than computational, which many candidates find a useful change of pace after FAR, and it builds directly on the financial-reporting foundation FAR provides, because you cannot audit statements you do not understand.
What AUD covers
The section walks through the audit process end to end: accepting an engagement, assessing risk, planning, understanding and testing internal control, gathering audit evidence, and forming and reporting an opinion. Two ideas anchor everything. Independence is the auditor’s freedom from relationships or interests that would compromise objectivity, and it is non-negotiable, because an audit is only worth anything if the auditor is genuinely impartial. Professional scepticism is the questioning mindset that assumes nothing and corroborates claims with evidence. You also study the ethics rules that govern the profession, the different levels of assurance (an audit gives reasonable assurance, a review gives limited assurance, and other engagements give still less), and how the wording of the auditor’s report changes with the findings.
Why it matters and a worked idea
AUD tests whether you think like an auditor, which is why its questions so often ask what you should do next rather than what a term means. The reasoning pattern to internalise is: identify where the risk of material misstatement is highest, then direct the most evidence-gathering effort there. As a teaching example of that pattern: if a company’s revenue recognition involves significant management estimates, an auditor treats that as a higher-risk area and gathers more persuasive evidence around it, rather than testing every account with equal effort, and a simulation that asks you to plan the response is testing whether you let assessed risk drive the audit. Study AUD by following the logic of the process, because rote lists of procedures do not survive contact with the scenario questions.
Chapter 4: Core - REG (Taxation and Regulation)
REG covers US federal taxation together with the business law and ethics that surround professional practice. It is detail-heavy, especially the tax rules, and it is the Core section where currency matters most, because tax law changes and the exam tests the rules in force. This is also the section most directly extended by one of the Disciplines (TCP), so a strong REG foundation pays off if you take that route.
What REG covers
The taxation material is the bulk of the section and spans the taxation of individuals and of entities (sole proprietorships, partnerships, corporations including S corporations, and trusts and estates), property transactions, and the professional responsibilities and ethics governing tax practice, including the rules a practitioner must follow. The business law portion covers areas such as contracts, agency, debtor-creditor relationships, and business structures. A recurring tax concept worth singling out is basis, the amount, usually starting from cost and adjusted over time, used to figure gain or loss on a sale and to compute depreciation; getting basis right is the hinge of a large share of property and entity questions.
Why it matters and how to study it
REG rewards precise, current knowledge applied to fact patterns, which is why it suits structured study and frequent practice. The trap is studying outdated material or treating tax as pure memorisation; the simulations give you a scenario and expect you to compute the right tax result under the current rules. As a teaching example of basis reasoning: when an owner sells property, the taxable gain is the amount realised minus the adjusted basis, so two sales at the same price can produce very different taxable gains depending on each asset’s basis history, and a simulation that hands you the purchase price, improvements, and depreciation is testing whether you can track basis to the right number. Keep your materials current, because relying on prior-year rules is a self-inflicted error on this section above all.
Chapter 5: The Discipline sections (choose one)
The fourth section is a single Discipline you choose, and all three lead to the same CPA licence; the choice is about depth and fit, not about a lesser or greater qualification. Pick the one that matches your career direction, and where possible the one that overlaps a Core section you have just passed, so the knowledge carries over while it is fresh.
BAR - Business Analysis and Reporting
BAR goes deeper into financial reporting, analysis, and the more technical accounting topics, extending FAR. It suits candidates heading toward roles in financial reporting, financial planning and analysis, or technical accounting, and it pairs naturally with FAR because the underlying standards and statement knowledge overlap. If you found FAR’s reporting material the most natural of the Core sections, BAR is the logical continuation.
ISC - Information Systems and Controls
ISC focuses on information systems, IT controls, data, and security, and on the controls relevant to system and organisation control (SOC) engagements. It extends the controls and risk thinking from AUD into the technology domain, and it suits candidates drawn to IT audit, controls, and assurance over systems. As the profession’s work becomes more technology-driven, this Discipline reflects a growing area of demand.
TCP - Tax Compliance and Planning
TCP goes deeper into taxation, including more complex individual and entity tax compliance and tax planning, extending REG. It is the natural choice for candidates heading into tax practice, and it pairs with REG because the foundational tax rules carry straight over. If REG’s tax material is where you want to build your career, taking TCP soon after REG lets you compound that knowledge rather than relearn it.
Chapter 6: The credit window and licensure logistics
The CPA’s distinctive planning challenge is not any single section but the way the four fit together against a clock, and against your state board’s rules. Getting this framework right is as important as the content, because the costliest mistakes on the CPA are administrative, not academic.
How the rolling credit window works
You pass the four sections one at a time, and passing your first section starts a rolling credit window within which the remaining three must be passed or you lose credit for the expired section and must retake it. Following the 2023 NASBA decision, that window is commonly 30 months, extended from the long-standing 18 months, but adoption is state by state, so some boards may still apply 18 months and you must confirm your own board’s rule. The practical consequence is the same either way: sequence your sections so a single bad month does not cascade into lost credit, and keep buffer for a possible retake. Treat the window as part of your exam strategy from day one, not an afterthought.
Eligibility and the 150-hour rule
Because the CPA is a state licence, your board sets the entry rules, most commonly 150 semester credit hours of education including specified accounting and business courses, which is more than a standard bachelor’s degree provides and often requires extra coursework or a master’s. Some states let you sit the exam at 120 hours but require 150 for licensure; others require 150 to sit. Sorting this out before you book decides when you can start at all, and it is the step most candidates underestimate. International candidates face the same state-by-state reality and should check their chosen board’s coursework rules early.
From passing to licensed
Passing all four sections is the exam milestone, but licensure also requires the experience component, typically a period of supervised work verified by a licensed CPA, plus any ethics exam your state mandates. Plan the experience alongside or after the exams rather than treating the exam pass as the finish line. The clean sequence is: confirm eligibility, pass the four sections inside your window, then complete the experience and any ethics requirement to obtain the licence.
Chapter 7: Study plan and timeline
With the content and the logistics understood, the remaining work is pacing the four sections so the calendar serves you. Three facts drive the plan: there are four sections, the credit window starts at your first pass, and each section is a serious block of hours in its own right.
Budget the hours and choose an order
Plan for roughly 300 to 400 hours in total across the four sections, about 80 to 120 hours each, with the broadest sections taking the upper end. There is no mandated order, but a widely used one is FAR first, then AUD, then REG, then your Discipline. The logic: FAR is the broadest and often hardest, so clearing it while motivation is high and before the window applies to the rest removes the biggest hurdle early; AUD builds on FAR’s reporting foundation; REG sits comfortably in the middle; and saving the Discipline for last lets you pair it with the Core section it overlaps (TCP after REG, BAR after FAR, or ISC after AUD). Decide deliberately rather than drifting, because the order interacts with the window.
A per-section rhythm
A single section takes most self-studiers about ten to twelve weeks at ten to twelve hours a week; an intensive run compresses that to six to eight weeks at a higher weekly load, which suits FAR or candidates studying between jobs. Whichever pace you choose, reserve the final two to three weeks for timed practice across both multiple-choice questions and task-based simulations, and sit a full section mock before booking the real thing. At one section roughly every three to four months you finish in about twelve to fourteen months, leaving comfortable buffer inside the credit window for a retake. To turn this into dated weeks for your own start date and section list, use the free study-plan generator. If you are still weighing the CPA against the other major finance credential before committing this much time, the CFA vs CPA comparison covers how the two differ in career path, structure, and cost.
Practise simulations, not just multiple-choice
The most common way candidates lose marks is by drilling multiple-choice and neglecting task-based simulations, which carry significant weight and test whether you can actually do the work. Build simulations into every study block: practise routing figures into the correct schedules, interpreting source documents, and using the authoritative-literature search, all under time, so the real interface holds no surprises. Most candidates also use a structured review course; whether or not you do, the principle is the same, namely that simulation practice is where exam readiness is really built.
Chapter 8: Final preparation, exam day, and format
Final preparation
In the last weeks before each section, shift from learning to timed, full-section practice across both question types, and aim to be scoring consistently above the 75 pass line on fresh material before you book. Review not just whether you got a question right but why the correct treatment is correct, because that reasoning is what the simulations reward. Keep your REG and Discipline-tax materials current, since tax rules change, and confirm your section’s blueprint against the AICPA before exam day so no recent change catches you out.
Managing the window across sections
Between sections, keep the credit window in view: only sit a section when your practice scores are ready, space your dates so one bad week does not cascade, and protect buffer for a retake, because losing credit for a section you already passed is the costliest mistake on this exam. The calendar discipline you apply between sections matters as much as the studying within them.
Exam day and format
On the day, each section is a roughly four-hour exam at a Prometric test centre, scheduled within a testing window, and you will need your Notice to Schedule and government-issued identification. Each section mixes multiple-choice questions with task-based simulations, and the passing score is 75 on a 0 to 99 scale. Pace yourself so the simulations, which take longer than multiple-choice, get the time they need, and apply the disciplined reading you practised: identify the correct treatment or the right next step, support it with the framework, and work the simulation cleanly. Having prepared at full length, kept your materials current, and confirmed the rules with your state board and the AICPA, the format will feel familiar rather than overwhelming, which is exactly the advantage the preparation was meant to buy.
