6.2 Last-Week Review Map
Key Takeaways
Foundations of Internal Auditing is the heaviest section at 35% — master the audit charter and the function's mandate.
Governance, Risk Management, and Control carries 30% — master COSO and the Three Lines Model.
Ethics and Professionalism (20%) covers Domain II's five principles: integrity, objectivity, competency, due professional care, and confidentiality.
Fraud Risks (15%) tests the fraud triangle: motivation, opportunity, and rationalization.
The final week is for consolidation, not new resources — review high-weight weak sections first.
Study by weight, not by chapter order
With one week left, spend your hours where the points are. CIA Part 1 is built on four sections, and their exam weights are unequal. Reviewing them in proportion to weight — and starting with your weakest high-weight section — is the highest-return use of the final week.
| Section | Domain | Weight | Approx. questions | Anchor to review |
|---|---|---|---|---|
| A | Foundations of Internal Auditing | 35% | ~44 | The audit charter and the function's purpose, authority, and mandate |
| B | Ethics and Professionalism | 20% | ~25 | Objectivity (the 12-month rule, gifts) + due professional care |
| C | Governance, Risk Management, and Control | 30% | ~38 | COSO frameworks + the Three Lines Model |
| D | Fraud Risks | 15% | ~19 | The fraud triangle: motivation, opportunity, rationalization |
Note the imbalance: Section A (Foundations) is the largest at 35% — more than one in three questions — followed closely by Section C (Governance, Risk Management, and Control) at 30%. Together they account for nearly two-thirds of the exam, so they deserve the most review minutes. The exam is based on the IIA's Global Internal Audit Standards (effective 9 January 2025), which reframed the prior Standards into a principles-based structure; the exam still tests the same core concepts of purpose, ethics, competency, and governance.
High-yield recap: Section A — Foundations (35%)
The internal audit charter is the formal document that records the function's mandate (its authority, role, and responsibilities), organizational position, reporting relationships, and the scope and types of services; it is approved by the board. Know the GIAS Purpose of Internal Auditing — strengthening the organization's ability to create, protect, and sustain value through independent, risk-based, and objective assurance, advice, insight, and foresight — and the difference between assurance engagements (three parties: auditor, auditee, user) and advisory engagements (two parties, scope agreed with the client).
Foundations now also absorbs much of the former independence material. Independence is organizational (freedom from conditions that threaten the function's ability to carry out responsibilities); the defining tested fact is that the Chief Audit Executive (CAE) reports functionally to the board and administratively to senior management. Functional oversight includes approving the charter, the risk-based plan, and the budget, and authorizing the CAE's appointment or removal. Competency (tested in Section B) can be met collectively: the CAE must ensure the function possesses or obtains the competencies it needs, so an individual auditor need not have every skill.
High-yield recap: Section B — Ethics and Professionalism (20%)
This section carries the integrity, objectivity, competency, due professional care, and confidentiality material. Objectivity is the individual auditor's unbiased mental attitude, free from conflicts of interest. Due professional care means the care and skill of a reasonably prudent and competent auditor; it is not a guarantee that all risks or errors will be found. Auditors maintain proficiency through continuing professional development (CPD/CPE).
Quality rules (the QAIP and the five-yearly external assessment) are Part 3 content in the 2025 syllabus. For Part 1, know the 12-month rule: objectivity is presumed impaired if an auditor provides assurance on an activity they were responsible for within the previous 12 months.
High-yield recap: Section C — Governance, Risk Management, and Control (30%)
Master two frameworks. COSO publishes the Internal Control – Integrated Framework (five components: control environment, risk assessment, control activities, information and communication, monitoring) and Enterprise Risk Management. All five components must be present and functioning for a system of internal control to be considered effective. The Three Lines Model (IIA, 2020) replaces the old "three lines of defense": first line = operational management owning and managing risk; second line = risk and compliance functions; third line = internal audit providing independent, objective assurance and advice to management and the governing body.
Know COSO's risk responses: accept, avoid, pursue, reduce, and share; and control types: preventive, detective, and corrective. Be precise about a few distinctions the exam loves. Risk appetite is the broad amount of risk an organization is willing to accept in pursuit of value; risk tolerance is the narrower acceptable variation around a specific objective. Inherent risk is the risk before controls; residual risk is what remains after controls operate.
The board sets the tone and owns oversight, management owns and operates the controls, and internal audit provides independent assurance — never owning the controls it audits.
High-yield recap: Section D — Fraud Risks (15%)
The fraud triangle explains why fraud occurs through three conditions: motivation (pressure: a financial or personal incentive), opportunity (weak controls that let it happen), and rationalization (the offender justifying the act). Separate the auditor's role from management's: management is responsible for establishing controls to prevent and detect fraud, while internal audit evaluates the potential for fraud and how the organization detects and manages fraud risks and considers specific fraud risks when planning each engagement. Know red flags and the auditor's duty to exercise professional skepticism.
Final-week discipline
Use short mixed-section sets rather than re-reading one chapter end to end, so your brain practices switching context the way the real exam forces you to. Stop adding new resources in the last few days — a calm review of your error log beats a frantic new course outline. Finally, hold the line that due professional care does not mean infallibility: an auditor who applies reasonable care can still miss an irregularity and remain in conformance.
Weight your final hours toward the two largest sections, Foundations (35%) and Governance/Risk/Control (30%), without neglecting the fraud triangle and the 12-month objectivity rule.
