Feature
Courseiva
This free ISC practice test mirrors the structure and difficulty of the real (ISC)2 Information Systems Security Engineering Professional (CISSP-ISSEP, Aug 2025 blueprint) (ISC) exam. Every question is written against the official 2026 exam blueprint published by (ISC)², ensuring you practise exactly what the exam tests — not last year's objectives.
The ISC blueprint is divided into 5weighted domains. Questions on this page are distributed proportionally across each domain, so the mix you see here reflects the same weighting you'll face on exam day. High-weight domains like Risk Management and Secure Operations Change Management And Disposal contribute the most questions, meaning focused practice on these areas gives you the highest return on study time.
ISC Exam Blueprint — 5 Domains
Risk Management
Secure Operations Change Management And Disposal
Security Planning And Engineering
Systems Security Engineering Foundations
Systems Security Implementation Verification And Validation
17 numbered sets, 5 domain question banks, and targeted sessions — every page is a unique set of questions.
Choose all correct answers
Each chapter page covers one topic in depth — theory, key concepts, and focused practice questions. Use these to close knowledge gaps before returning to full practice tests.
Getting the most from practice questions requires more than just clicking through answers. Here is the study method used by candidates who pass ISC on their first attempt:
Answer before revealing
Read each ISC question fully, eliminate obviously wrong choices, then commit to an answer before clicking to reveal. This active recall process is what builds lasting knowledge.
Read every explanation
Even when you answer correctly, read the full explanation. Knowing WHY the right answer is correct — and why the distractors are wrong — is what separates a 750 score from a 900 score.
Track weak domains
Note which ISC domains you get wrong most often. Then do a targeted 20-30 question session focused only on that domain until your accuracy improves.
Simulate exam pacing
The real ISC gives you roughly 0.6 minutes per question. Use the 60 or 120-question sessions to practise hitting that pace comfortably.
Most candidates who pass ISC on their first attempt report doing between 400 and 800 practice questions over 4–8 weeks of preparation. With 209+ questions in the Courseiva bank, you have more than enough material to build that repetition without seeing the same question twice.

Answer all 20 questions to see your domain score breakdown
A structured study plan dramatically increases your chances of passing ISC on the first attempt. The most effective approach combines reading the official (ISC)² documentation or a study guide, watching video explanations for difficult concepts, and then reinforcing everything with daily practice questions.
We recommend the following weekly structure for ISC preparation:
Cover each ISC domain systematically. Read the exam objectives, watch explanatory content, and do 10–20 practice questions per domain to test understanding as you go.
Run full 50–60 question mixed sessions daily. Review every wrong answer in detail. Identify which domains are consistently scoring below 70% and revisit those study materials.
Do 100–120 question timed sessions to simulate real exam conditions. Aim for consistent scores above 80% before booking your exam date. A score above 80% in practice typically translates to a passing ISC score.
On exam day, the ISC tests your ability to apply knowledge to realistic scenarios — not just recall definitions. This is why reading explanations and understanding the reasoning behind every answer matters more than simply grinding question volume. Use the high-count sessions (100, 120) in the final weeks as your confidence benchmark.

Scaled scoring
The ISC exam uses a scaled scoring system — your raw score of correct answers is converted to a score out of 1000. A passing score of 700/1000 does not mean you need 70% of questions correct; the conversion accounts for question difficulty. Consistently scoring above 75–80% on practice tests puts you in a strong position to achieve 700/1000 on the real exam.
Scenario-based questions covering exam objectives with detailed answer explanations.

No account required. Create a free account to unlock per-domain analytics and progress tracking across every certification on the platform. Courseiva is free forever, supported by advertising.
Every question is written against the official ISC exam blueprint published by (ISC)². Our questions follow the same wording style, scenario complexity, and answer structure as the actual exam. They are original questions — not brain dumps — so you learn the underlying concepts and reasoning, not just memorised answers. Candidates who study with brain dumps often pass but have no transferable knowledge; Courseiva questions make you genuinely competent.
Most candidates who pass ISC on their first attempt do 30–60 questions per day. Use the Quick 10 session for daily warm-ups when you are short on time. On study days, run a 50 or 60-question session to build stamina. Reserve 100 and 120-question sessions for the final two weeks when you want to simulate real exam conditions and benchmark your readiness.
The ISC covers 5 domains: Risk Management, Secure Operations Change Management And Disposal, Security Planning And Engineering, Systems Security Engineering Foundations, Systems Security Implementation Verification And Validation. Each domain carries a different weight, so allocate your study time accordingly. The highest-weighted domains — Risk Management and Secure Operations Change Management And Disposal — should receive the most attention.
Exam dumps are memorised question-and-answer lists taken from actual exam papers, often obtained illegally and shared without (ISC)²'s authorisation. Using them violates your NDA and (ISC)²'s certification agreement, and can result in certification revocation. Courseiva questions are 100% original — written by certified engineers to test the same knowledge areas using new scenarios and wording. You learn the material, not just the answers.
Per-domain analytics, spaced repetition, daily challenges — and every other certification on the platform.
