How to study for the CISA: schedule, study plan & tips
To pass the CISA, plan 3–5 months at ~8 hours/week: cover all 5 domains with extra weight on Domains 4 and 5 (26% each), drill MCQs by domain, then run timed 4-hour mock exams until you clear 75% before booking.
Week-by-week schedule
| Period | Goal | What to do |
|---|---|---|
| Weeks 1–6 | Domains 1–3 | IS audit process, IT governance, acquisition/development. Read + 30 MCQs per domain. Capture ISACA terminology. |
| Weeks 7–12 | Domains 4 & 5 (the heaviest) | Operations/resilience and asset protection: 52% of the exam combined. Double your question time here. |
| Weeks 13–16 | Mocks & targeted review | Full 4-hour mocks, error log, spaced repetition on weak spots. Book once you stably clear 75%. |
Tips to maximize your odds
- •Weight your study by exam weighting: D4 and D5 first (26% each).
- •Think “ISACA best practice”, not “what I’d do” — the expected answer follows the framework.
- •Train endurance: 150 questions in 4 hours is a marathon — do full-length mocks.
- •Error log + spaced repetition on the technical vocabulary.
Mistakes to avoid
- ✕Studying all 5 domains equally when D4+D5 are more than half the exam.
- ✕Answering from personal experience instead of the ISACA framework.
- ✕Never simulating the full 4 hours before exam day.
