CPA Audit Exam Cheat Sheet: Risk, Assertions, Controls, and Opinions for AUD
The frameworks and decision rules that come up again and again on the Auditing and Attestation (AUD) section.
AUD at a glance: The Auditing and Attestation section is a 4-hour exam with multiple-choice questions and task-based simulations, each weighted at about half the score. A scaled score of 75 is required to pass. This CPA audit exam cheat sheet covers the frameworks behind most questions. Always check the current AICPA blueprint for exact weights.
AUD is less about calculations and more about frameworks: when to do what, and what kind of report results. A tight CPA audit exam cheat sheet helps you memorize the decision rules that drive most answers.
AUD Blueprint Areas
| Area | Approx. weight |
|---|---|
| I. Ethics, Professional Responsibilities and General Principles | 15–25% |
| II. Assessing Risk and Developing a Planned Response | 25–35% |
| III. Performing Further Procedures and Obtaining Evidence | 30–40% |
| IV. Forming Conclusions and Reporting | 10–20% |
CPA Audit Exam Cheat Sheet: The Audit Risk Model
- Audit risk (AR) = Inherent risk (IR) × Control risk (CR) × Detection risk (DR).
- Risk of material misstatement (RMM) = IR × CR. The auditor assesses it but can’t change it.
- Detection risk is the only component the auditor controls — through the nature, timing, and extent of procedures.
- Inverse relationship: Higher RMM → lower acceptable detection risk → more (or stronger) substantive testing.
Management Assertions
| Transactions and events | Account balances |
|---|---|
| Occurrence | Existence |
| Completeness | Completeness |
| Accuracy | Accuracy, valuation, and allocation |
| Cutoff | Rights and obligations |
| Classification | Classification |
| Presentation | Presentation |
Internal Control (COSO)
The five COSO components — remember CRIME:
- C — Control environment: Tone at the top, integrity, and structure.
- R — Risk assessment: Identifying and analyzing risks to objectives.
- I — Information and communication: Getting the right information to the right people.
- M — Monitoring activities: Ongoing and separate evaluations.
- E — (Control) activities: Policies and procedures such as approvals, reconciliations, and segregation of duties.
Audit Opinions
| Issue | Material, not pervasive | Material and pervasive |
|---|---|---|
| Financial statements are materially misstated | Qualified | Adverse |
| Unable to obtain sufficient appropriate evidence | Qualified | Disclaimer |
When there’s no material issue, the auditor issues an unmodified opinion. Emphasis-of-matter and other-matter paragraphs add information without changing the opinion, and a substantial doubt about going concern is reported in its own section.
Reviews, Compilations, and Preparations
Review
Provides limited assurance, mainly through inquiry and analytical procedures. Independence is required.
Compilation
Provides no assurance. The accountant assists in presenting financial information; a lack of independence must be disclosed.
Preparation
Provides no assurance and no report is required, but each page indicates that no assurance is provided.
Key Takeaways
- Audit risk = inherent risk × control risk × detection risk; only detection risk is controlled by the auditor.
- Know the assertions and the direction of testing for existence vs. completeness.
- Remember the five COSO components with CRIME.
- Use the opinion table: misstatement → qualified or adverse; scope limitation → qualified or disclaimer.
- Reviews give limited assurance; compilations and preparations give none.
Frequently Asked Questions
What is on the CPA AUD exam?
The Auditing and Attestation section covers ethics and professional responsibilities, assessing risk and planning, performing procedures and obtaining evidence, and forming conclusions and reporting, using multiple-choice questions and task-based simulations.

When does an auditor issue a disclaimer of opinion?
When the auditor can’t obtain sufficient appropriate evidence and the possible effects are both material and pervasive.
