CPA AUD Study Guide: Blueprint, Topics and a Study Plan

AUD is the section candidates most often describe as the one they cannot revise for. The material feels readable, the practice questions feel fair, and then the score comes back at 71.

There is a structural reason for that, and it is visible in the Blueprint. AUD is the only CPA section with an Evaluation component. Every other section tops out at Analysis. AUD asks you to judge whether something is sufficient, appropriate or reasonable, and no amount of knowing the standards produces that skill on its own.

This guide covers what is on the blueprint, why AUD's questions behave differently from FAR's, and how to study a section that rewards judgement over computation.

What AUD covers

Area	Weight	What sits inside it
I. Ethics, Professional Responsibilities and General Principles	15 to 25%	Independence, the AICPA Code, engagement acceptance, quality management, documentation, communication with those charged with governance
II. Assessing Risk and Developing a Planned Response	25 to 35%	Understanding the entity, internal control, materiality, risk of material misstatement, fraud risk, planning the audit
III. Performing Further Procedures and Obtaining Evidence	30 to 40%	Tests of controls, substantive procedures, sampling, confirmations, estimates, related parties, subsequent events
IV. Forming Conclusions and Reporting	10 to 20%	Audit opinions and their modifications, emphasis and other-matter paragraphs, reports on other engagements

Areas II and III together are 55 to 75% of the exam, and they are one continuous idea rather than two topics: you assess a risk, then you design a procedure that responds to it. Almost every substantial AUD question is somewhere on that chain, and candidates who study procedures as a list divorced from the risks that motivate them find those questions nearly unanswerable.

Area IV is small in weight and large in visibility. Reporting is the part of auditing everyone has seen, so candidates over-invest in it. Twenty percent at the very top of the range is worth securing, but not at the expense of the risk-and-response chain that is three times the size.

The Evaluation component is the whole difficulty

AUD's skill allocation is roughly 30 to 40% Remembering and Understanding, 30 to 40% Application, 15 to 25% Analysis, and 5 to 15% Evaluation.

Compare that to FAR, which has no Evaluation at all and puts only 5 to 15% at the Remembering and Understanding level. The two sections are near mirror images, and they need to be studied differently.

The higher recall component is why AUD feels approachable early: there genuinely is more that can be learned outright. The Evaluation component is why it stops feeling approachable around the 70 mark. Evaluation questions ask whether the evidence obtained was sufficient, whether a conclusion was appropriate, whether a response was adequate. Those have defensible answers, but not answers you can derive from a formula.

How the exam is built

Item	AUD
Length	4 hours
Multiple choice questions	78
Task-based simulations	7
Score weighting	50% MCQ, 50% TBS
Testing availability	Continuous, as a Core section
2026 pass rate	48.65% cumulative
Skill allocation	Remembering and understanding 30 to 40%, application 30 to 40%, analysis 15 to 25%, evaluation 5 to 15%
Passing score	75 on a 0 to 99 scale
Credit window	30 months from the score release of your first passed section, adopted board by board

78 multiple choice questions is the most of any Core section, and it changes the time arithmetic completely. At roughly a minute and a quarter each, the MCQ testlets consume about a hundred minutes, leaving around two hours for seven simulations. AUD is a pace problem in a way FAR is not: there are simply a lot of questions to read, and AUD questions are wordy.

Why AUD questions behave differently

This is the part worth more than any topic list, because it is what candidates repeatedly fail to adjust to.

The qualifier is the question. AUD stems are full of words like "most likely", "least likely", "best", "primary" and "first". These are not padding. Several options will be things an auditor might legitimately do; the question is which one the standards point to first, or which one most directly addresses the risk described. Reading the stem twice is not a luxury in AUD.

Facts are given for a reason. When a question tells you the client is a first-year audit, or that the CFO resigned mid-year, or that inventory is held at a third-party location, that detail is the hinge. In FAR the numbers are the question; in AUD the circumstances are.

Two right answers usually means you missed a distinction. If you find yourself unable to separate two options, the distinction is nearly always between a test of controls and a substantive procedure, between sufficiency and appropriateness of evidence, or between what the auditor does and what management does. Those three confusions account for a large share of lost AUD marks.

The topics that decide the result

The risk-to-response chain

Understand the entity, identify what could go materially wrong, assess the risk, then design a procedure proportionate to it. If you can articulate why a specific procedure answers a specific risk, most of Areas II and III becomes tractable. If you have memorised procedures without their risks, it does not.

Internal control and tests of controls

The most reliably confused topic in the section. A test of controls asks whether the control operated; a substantive test asks whether the balance is right. Whether you can rely on controls changes how much substantive work you need, which is the link candidates miss.

Evidence: sufficiency and appropriateness

Sufficiency is quantity, appropriateness is quality, and appropriateness splits into relevance and reliability. Nearly every Evaluation-level question in AUD is testing one of those four words. Learning them as a precise vocabulary rather than as synonyms for "good evidence" is worth real marks.

Audit opinions and reporting

Reporting is the most mechanical part of AUD and should be secured completely, because it is decidable. The opinion follows from a two-by-two grid: is the problem a misstatement or a scope limitation, and is it material or material and pervasive?

Independence and ethics

Area I is rules driven and therefore cheap to secure. Independence questions in particular tend to be decidable: a specific relationship either impairs independence or does not. Learn the prohibited relationships and services properly and Area I stops being a source of loss.

A study plan

Eight to ten weeks at twelve to fifteen hours is a reasonable shape for AUD, and unlike FAR the order genuinely matters, because the section is one argument from start to finish.

Weeks	Focus	Why here
1	Ethics, independence, engagement acceptance, quality management	Rules driven and self-contained. Secure it early and stop thinking about it.
2 to 3	Understanding the entity, internal control, materiality, risk assessment	Everything in Area III responds to what you learn here. Studying procedures first is studying answers without questions.
4 to 5	Further procedures, evidence, sampling, confirmations, estimates	The largest area, and only sensible once risk is understood.
6	Conclusions, opinions and reporting	Decidable material. Secure it completely rather than approximately.
7	Other engagements: reviews, compilations, attestation, SOC at a high level	Frequently under-studied and reliably examined.
8 to 9	Simulations under time, then full mocks	Half the marks, and the place Evaluation-level questions live.

Two habits that matter more in AUD than elsewhere:

1. Review the questions you got right for the wrong reason. In a section with plausible distractors, guessing correctly is not knowledge, and it hides a gap that will reappear on exam day. Mark them.
2. Write down why the wrong option was wrong. AUD explanations are worth more than AUD questions. If you cannot articulate why the second-best answer is second-best, you have not learned the distinction the question was testing.

When to sit AUD

AUD is comparatively self-contained. It does not depend on FAR the way BAR does, and it does not feed a Discipline the way REG feeds TCP, which makes it the section most safely left towards the end of your credit window. Its pass rate is also modestly helped by that: candidates sitting AUD have usually sat something else first and know how the exam asks questions.

What should not be left late is your Discipline, which is only offered in the first month of each quarter. See Sequencing the CPA Exam Around the Discipline Windows.

Where to practise this

AUD rewards volume of well-explained questions more than almost any other section, because the learning happens in the explanation rather than in the answer. Prepito's AUD course covers the full blueprint with practice questions, timed simulations, full explanations and mistake review, in English.

CPA questions and written explanations are in English. Prepito’s interface is available in English and Arabic, and the AI tutor can respond in either language.

If you are planning the whole qualification, see the FAR study guide for the section most candidates take first, or the CPA programme.
