CISSP preparation guide
Choose a CISSP study plan you can sustain
Start with your available study hours and an honest coverage check. Use 30 days for focused consolidation only if you already have broad coverage; allow a longer window when you still need substantial concept study. Each schedule below includes review and unfamiliar mixed practice, not just a daily question target.

Which window matches the work you have left?
These are illustrative planning choices, not validated completion times or pass guarantees. ISC2’s outline defines the breadth you need to consider; it does not prescribe one preparation schedule.
The hours below are assumptions for these examples, not exam-body recommendations. Choose a sustainable schedule, then change it when your review reveals more work than you allowed for.
| Window | Weekly time | Best use | Main caution |
|---|---|---|---|
| 30 days | 10–12 hours | Consolidate broad prior study and repair a bounded set of gaps | Too short if large parts of the outline are new |
| 60 days | 7–9 hours | Alternate concept study with practice and review | Review can disappear if only new questions count |
| 90 days | 5–7 hours | Build gradual coverage alongside work | Long gaps between revisits disguise lost recall |
What goes into each schedule?
30 days: Days 1–3: compare your existing knowledge with all eight domains and take a baseline. Days 4–17: alternate the largest gaps with mixed retrieval, reserving part of each session for explanation review. Days 18–25: practise unfamiliar mixed scenarios and investigate recurring errors. Days 26–30: revisit unresolved distinctions, check exam logistics and protect rest. Do not cram a new full course into the final week.
60 days: Week 1: coverage inventory and baseline. Weeks 2–5: concept study, targeted practice and a weekly mixed check. Weeks 6–7: mixed practice with a written explanation of recurring misses. Week 8 and the remaining days: revisit unresolved topics and make a realistic decision about your remaining preparation needs. Do not infer readiness from improved scores on familiar questions.
90 days: Weeks 1–2: inventory and baseline, then identify unfamiliar areas. Weeks 3–8: build coverage while returning to earlier topics every week. Weeks 9–11: increase mixed practice and compare current errors with earlier ones. Weeks 12–13: repair the remaining gaps and prepare for exam-day logistics. Review time remains part of the plan throughout.
What does a seven-hour week look like?
The total is seven hours. The question count is deliberately unspecified: a difficult explanation can deserve more time than several easy answers. Finishing fewer questions with better understanding can be the correct outcome for a session.
| Day | Time | Work |
|---|---|---|
| Monday | 60 min | Learn one weak concept and explain it without notes |
| Tuesday | 60 min | Targeted questions and review of tempting alternatives |
| Wednesday | 30 min | Revisit last week’s missed distinctions |
| Thursday | 60 min | Study another domain; connect it to the first topic |
| Friday | 30 min | Clear unresolved review notes, not another full set |
| Saturday | 120 min | Mixed practice, then a separate review block |
| Sunday | 60 min | Check coverage, explain recurring misses and adjust next week |
How should CertArc change the plan?
After the baseline, inspect what lies behind a miss before scheduling more practice. If you did not know the concept, return to study material. If you knew it but chose an action outside the scenario’s scope, compare the alternatives and write the distinction you overlooked. These are different study tasks.
Use CertArc’s review and domain evidence to inform your next block. Its calendar can organize scheduled practice, but a scheduled date does not prove that you are ready or override module prerequisites. The initial baseline is small; strengthen the picture with later practice rather than treating one domain percentage as a verdict.
What if you miss a session?
Do not automatically double tomorrow’s workload. Identify what slipped: concept study, new practice or unresolved review. Keep essential review in the next available block and move lower-priority new work. If the same shortfall repeats, reduce the weekly commitment or reconsider the preparation window.
For example, if Tuesday’s hour was lost, use Wednesday’s thirty minutes to revisit the key concept and Thursday’s first thirty minutes for targeted practice. Move Thursday’s second topic to Sunday or the following week. This trades breadth that week for completing one useful learning cycle; it is an example, not an app scheduling rule.
Questions before you start
Should I study only weak domains?
No. Prioritize gaps while retaining checks across the outline. A small practice sample can make a familiar domain look stronger than it is.
Should every day include an exam?
Not necessarily. Some days need concept study or explanation review. A repeated score on familiar items is not the same as applying the concept elsewhere.
Can CertArc tell me to book the exam?
Practice evidence can inform your judgment but does not certify readiness or guarantee a result. Check official logistics and your remaining gaps independently.
Does the free path cover a 90-day plan?
No. CertArc’s free access is 21 days after onboarding. It includes a baseline, one sprint per domain and one short practice exam; a longer study plan may use other resources or paid access.
Where should I start if I cannot choose a schedule?
