How to study for the CIA: schedule, study plan & tips
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.
Week-by-week schedule
| 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. |
Tips to maximize your odds
- •One part at a time: book and sit each part before starting the next.
- •The winning ratio is ~40% reading / 60% questions. You learn the CIA by drilling MCQs.
- •Keep an error log: every missed question plus the reason. Re-read it before the exam.
- •Simulate the real thing: timed mock exams, no pauses, no notes.
- •Hit 75%+ on mocks before booking — the real cut score (600/750) is tougher than it looks.
Mistakes to avoid
- ✕Reading everything but never drilling questions — the #1 trap.
- ✕Booking all three parts at once and piling on pressure.
- ✕Ignoring rationales for the correct answers (not just the wrong ones).
