How to practise 100 CSCS questions when the real test is 50
The CITB Health, Safety and Environment test is a fixed 50 questions in 45 minutes, and that is exactly the format of our free 50-question mock test. There is no single 100-question CSCS exam, so think of 100 questions as a practice target rather than a test format. There are two honest ways to hit it.
Volume is the unsung lever in CSCS preparation. A candidate who has answered 50 questions has seen roughly 50 distinct topic angles. Work through 100 or more and you see close to twice that, and the extra coverage is exactly what catches the edge-case questions on the real exam that decide a 45/50 from a 43/50.
Two ways to reach 100 questions of practice
- Retake the free 50-question mock test (free, no account). Each sitting is 50 questions drawn from the same official-syllabus bank, so two sittings is 100 questions and three is 150. It stays free however many times you take it. Start at the free mock test.
- Premium Practice by Topic, up to 100 questions per topic. Choose any one of the 21 CITB topics and drill 10, 25, 50 or 100 questions on it in a single session, with an AI explanation on every wrong answer. This focused high-volume drill is a Premium feature. See Practice by Topic.
Note: there is no free, single, mixed 100-question session across all 21 topics. The free route is the 50-question mock, retaken as often as you like; the 100-per-topic drill is Premium.
What the 21 CITB topics cover
The CITB Operatives syllabus is organised into five clusters across 21 detailed topics. However you build your volume, this is the ground your practice needs to cover:
- General responsibilities, duties under the Health and Safety at Work Act, induction, PPE, accident reporting and emergency procedures.
- Health and welfare, noise action values, COSHH, asbestos awareness, manual handling and welfare facilities.
- General safety, site induction, risk assessments, method statements, permits to work, signs and barriers.
- High-risk activities, working at height, excavations, confined spaces, electrical safety, plant and lifting, fire prevention.
- Environment, the waste hierarchy, spill response and sustainable site management.
Spread your practice across all five clusters so a weak area shows up before test day rather than on it.
Try some real CSCS questions
Here are six real practice questions and answers from the same bank, with the correct answer marked and a short explanation for each.
Q1. Which document outlines the potential hazards and control measures for a specific task?
- ✓Risk assessment.
- BSite diary.
- CWork schedule.
- DEmployee handbook.
Why: A risk assessment identifies potential hazards and outlines control measures to mitigate risks.
Q2. Which of these statements about welfare facilities is true?
- AWorkers are required to bring their own cleaning supplies for washing facilities.
- ✓Employers must provide facilities for workers to store and dry clothing.
- CToilets do not need to be separated by gender.
- DIt is acceptable to have no toilets on site for small builds.
Why: Employers must provide suitable facilities for workers to store and dry clothing.
Q3. Which of these signs would you expect to find near a high noise area?
- ✓Wear ear protection
- BNo entry
- CSlippery surface
- DFirst aid kit
Why: In high noise areas, a mandatory sign requiring ear protection will typically be displayed.
Q4. What is the purpose of a guardrail on a scaffold?
- ATo provide a handhold
- BTo prevent tools from falling
- ✓To prevent workers from falling
- DTo maintain balance
Why: Guardrails are designed to prevent workers from falling off the scaffold.
Q5. What is the purpose of a Residual Current Device (RCD)?
- ATo enhance the tool's power efficiency.
- ✓To protect the user from electric shock.
- CTo increase the speed of the tool.
- DTo reduce noise from the tool.
Why: An RCD quickly cuts off power to prevent serious electric shocks.
Q6. Why is it important to segregate waste on site?
- ATo increase landfill tax
- BTo discourage recycling
- ✓To improve recycling rates and reduce contamination
- DTo create more work for site staff
Why: Segregating waste enhances recycling efficiency by reducing contamination with non-recyclable materials.
When you are ready, take the full free 50-question mock test, or drill a single topic in depth such as PPE or working at height. Labourers can also use the Green Card mock test.
How to read your score
Apply the same 90% threshold as the real 50-question exam. On a 50-question mock, aim for 45/50 or higher. On a topic drill, 90%+ means you have that topic locked, while below 85% flags an area to revise before booking the real exam.
How 100 questions of practice fit into a 2-week plan
- Day 1. Sit a free 50-question mock test cold to establish your baseline. Note which topics scored lowest.
- Days 2-4. Read the official CITB revision book, focusing on your weakest topics.
- Day 5. Do a longer block: two free 50-question mocks back to back (100 questions), or a Premium 100-question drill on your weakest topic.
- Days 6-10. Targeted topic drills on whichever areas came out weakest.
- Day 11. Another 100-question block. By now you should be 90%+. If not, add a few more days of targeted study.
- Days 12-14. Two or three timed 50-question mocks to lock in pace. Aim for 95%+, then book the real test.
Good to know
- The mock test is genuinely free. 50 questions, no account, no card, retake as often as you like at the free mock test.
- 100 per topic is a Premium drill. Practice by Topic lets you run up to 100 questions on a single topic with AI explanations on every wrong answer.
- Same 90% standard. Mark yourself against the real 45/50 pass bar so your practice scores mean something.
- Pair volume with drills. Mocks find your weak topics; topic drills fix them. Use them together.
