A health and safety mock test is only useful if it copies the real test closely enough to show you where you stand. For the CITB Operatives test that means 50 multiple-choice questions in 45 minutes, and a practice benchmark of 45 out of 50, which matches the official 90% pass mark.
Five things a useful mock test should do
- Use the same number of questions and the same time limit as the official format.
- Cover the public topic areas, not only the subjects that are easy to write about.
- Explain why each answer is right or wrong, so that a wrong answer teaches something.
- Show your results by topic, so that you can see which area needs more work.
- Say clearly that a practice score is not an official result.
What a score does not tell you
A high practice score does not guarantee a pass, and a low one does not mean you will fail. Practice questions are a sample. Your real test will be different, and only CITB can give an official result. Be wary of any site that promises a pass or claims its questions are the real ones.
How to review a mock test properly
Reviewing a mock test matters more than sitting it. For each wrong or unsure answer, write down three things: the hazard in the question, the control that should have been chosen, and the reason the other options were weaker. Then do a short set on that topic within a day or two, so the reasoning sticks.
Where to start
Begin with the ten free questions, then read the test format so you know what the full paper looks like. The glossary covers the terms that come up most often.
