To pass the CIA, plan 200–300 total study hours across the three parts (roughly 65–100 hours per part), spread over 3–6 months while studying one part at a time: read each domain, drill topic-by-topic multiple-choice questions, then run timed mock exams until you consistently score above 75% before booking the real exam.
| Period | Goal | What to do |
|---|---|---|
| Weeks 1–4 | Learn — Part 1 | Read Essentials of Internal Auditing domain by domain. After each chapter, drill 20–30 targeted MCQs to lock in the concept. |
| Weeks 5–6 | Intensive drills — Part 1 | Question bank by domain, then 2–3 timed mock exams. Review every miss with its rationale. Book the exam once you clear 75%. |
| Weeks 7–10 | Part 2 — Practice of auditing | Same cycle: read, topic MCQs, then mocks. Part 2 is more applied — focus on engagement conduct and supervision. |
| Weeks 11–14 | Part 3 — Business knowledge | The broadest part (finance, IT, governance). Lean on spaced repetition for retention and finish with full-length mocks. |
Most candidates need 200 to 300 total study hours across all three parts — roughly 65 to 100 hours per part — typically spread over 3 to 6 months while studying one part at a time. An adaptive plan that targets your weak domains can shorten this.
A proven schedule is ~5–6 weeks per part: read each domain, drill topic MCQs, then run timed mocks until you score above 75%. Sit each part before starting the next.
Yes. To fit 200–300 hours into three months you need roughly 17–25 hours per week, focused heavily on question practice rather than passive reading. It is demanding but achievable for full-time students or candidates between roles.
Take Part 1 (Essentials of Internal Auditing) first — it builds the conceptual base the other parts assume.
Aim for at least 1,000–1,500 quality practice questions per part, reviewing the rationale on every miss. Volume plus review is what moves your mock score.
