Pacing calculator
This pacing calculator tells you whether you are on track to finish a 50-question, 45-minute practice test in time. You enter how many questions you have answered and how much time has passed, and it works out your average time per question and where you would finish at that speed. It is for practice only: it is not an official result, and this site is independent and not affiliated with CSCS or CITB.
Key takeaways
- The CITB Operatives page gives the test as 50 questions in 45 minutes, with a 90% pass mark (at least 45 of 50).
- Spread evenly, 45 minutes across 50 questions averages 54 seconds per question.
- 54 seconds is an average to plan around, not a limit on any single question.
- Your pace is your elapsed time divided by the number of questions answered.
- Your projected finish is that pace multiplied by 50, and you compare it with 45 minutes.
- Pacing practice is most useful alongside accuracy practice, because a fast but wrong score does not pass.
What the calculator does
The calculator takes two numbers from you:
- Questions answered so far. Count the questions you have completed, not the one you are working on.
- Time elapsed. Enter the minutes, and seconds if you have them, since you started.
From those it shows:
- Average time per question so far.
- Projected total time if you keep that pace for all 50 questions.
- Ahead or behind compared with an even pace of 54 seconds a question.
- Time left per remaining question, so you know the pace you need to finish.
It does not mark your answers and it does not predict whether you will pass. It only measures time. The result is a guide for your practice session, and nothing more.
The numbers behind it
All the maths starts from three figures stated on the CITB Operatives test page: 50 questions, 45 minutes and a 90% pass mark. For pacing only the first two matter.
| Figure | Value | Working |
|---|---|---|
| Total time in seconds | 2,700 | 45 minutes x 60 |
| Questions | 50 | From the CITB page |
| Even pace per question | 54 seconds | 2,700 / 50 |
Please check the CITB Operatives page for the current test details before you sit the real test, since the official page is the authority.
The formulas in plain text
You can do the sums without the calculator if you want to check it.
- Average per question = elapsed seconds / questions answered
- Projected total = average per question x 50
- Time allowed so far = questions answered x 54 seconds
- Ahead or behind = time allowed so far - elapsed seconds (positive means ahead, negative means behind)
- Pace needed for the rest = (2,700 - elapsed seconds) / (50 - questions answered)
If you are using a different practice test length, change the numbers in the same way: total seconds divided by total questions gives the even pace.
Worked examples
These examples show how the formulas work. They are illustrations of the arithmetic, not results the calculator produces for you.
| Answered | Elapsed | Average per question | Projected finish | Against 54 seconds each | Pace needed for the rest |
|---|---|---|---|---|---|
| 10 | 8 min 0 s | 48 seconds | 40 min 0 s | 1 min ahead | 55.5 seconds |
| 20 | 20 min 0 s | 60 seconds | 50 min 0 s | 2 min behind | 50 seconds |
| 25 | 21 min 0 s | 50.4 seconds | 42 min 0 s | 1 min 30 s ahead | 57.6 seconds |
| 30 | 28 min 0 s | 56 seconds | 46 min 40 s | 1 min behind | 51 seconds |
| 40 | 30 min 0 s | 45 seconds | 37 min 30 s | 6 min ahead | 90 seconds |
Take the second row. After 20 questions and 20 minutes you have 25 minutes left for 30 questions, which is 50 seconds each. If you keep going at 60 seconds each, you would finish at 50 minutes, which is 5 minutes over the 45.
Checkpoints for an even pace
If you prefer a simple timetable to a calculator, these checkpoints come from the 54-second average.
| Questions answered | Time on the clock |
|---|---|
| 10 | 9 minutes |
| 20 | 18 minutes |
| 25 | 22 minutes 30 seconds |
| 30 | 27 minutes |
| 40 | 36 minutes |
| 50 | 45 minutes |
If you are slightly ahead at each checkpoint, you have spare time. If you are behind, you will need to speed up on the remaining questions, but not by guessing.
How to use pacing in practice
Before you start
- Decide your checkpoints, for example the 10-question and 25-question marks above.
- Set a visible timer, such as the free mock test timer, so you do not have to do the sums mid-test.
- Read our guide on timing a 50-question CITB mock test for more on how to split your time.
During the test
- Check the clock at your checkpoints rather than after every question. Watching the clock too often costs time and focus.
- Do not spend a long time on one question. Make your best choice and move on if you are stuck.
- Remember that some questions take a few seconds and others take longer, so 54 seconds is only an average.
After the test
- Run the calculator with your final numbers to see your actual average.
- Compare speed with accuracy. If you finished early with a low score, slow down and read more carefully. If you scored well but ran out of time, practise recognising answers faster.
- Use the pass mark calculator on this site to turn your score into a percentage and compare it with the 90% benchmark.
Quick checklist
- [ ] I know the test details: 50 questions, 45 minutes, 90% to pass.
- [ ] I know my even pace is 54 seconds a question.
- [ ] I have noted two or three checkpoint times.
- [ ] I have a timer I can see without losing my place.
- [ ] I will not rush a question I can answer correctly with a little more thought.
- [ ] I will review my pace and my accuracy afterwards.
Limits of the calculator
- It assumes a constant pace, but real tests are uneven.
- It uses a 50-question, 45-minute format. If your practice paper is different, work out its even pace first.
- It cannot tell you whether the real test has any other rules or features. Check the CITB Operatives page for those.
- Its results are only as accurate as the numbers you enter.

Worked example: checking pace during one practice paper
This is an invented session. The numbers are there to show how to use the formulas on a real paper.
You start a 50 question practice paper and decide to check the clock at two points: after the first 12 questions, and after 30.
Check one. You have answered 12 questions and 10 minutes 30 seconds have passed, which is 630 seconds.
- Average per question: 630 / 12 = 52.5 seconds.
- Projected total: 52.5 x 50 = 2,625 seconds, or 43 minutes 45 seconds.
- Time allowed so far: 12 x 54 = 648 seconds, so you are 18 seconds ahead.
- Pace needed for the rest: (2,700 - 630) / 38 = about 54.5 seconds.
You are essentially on pace, so you change nothing.
Check two. You have answered 30 questions and 29 minutes have passed, which is 1,740 seconds.
- Average per question: 1,740 / 30 = 58 seconds.
- Projected total: 58 x 50 = 2,900 seconds, or 48 minutes 20 seconds.
- Time allowed so far: 30 x 54 = 1,620 seconds, so you are 120 seconds, or 2 minutes, behind.
- Pace needed for the rest: (2,700 - 1,740) / 20 = 48 seconds.
Now you know the position. You need about 48 seconds a question for the last 20, which is faster than your average so far. The sensible response is to stop lingering on any single question, make your best choice and move on, not to guess. A rushed wrong answer costs more than a few seconds, because the pass mark on the CITB Operatives page is 90%.
Reading pace and accuracy together
Pace on its own can mislead. After a practice paper, put your time next to your score and ask what the pair is telling you (general study advice, not an official CITB method).
| What happened | What it may mean | What to try |
|---|---|---|
| Finished early, score lower than you hoped | You may be reading too fast | Slow down and read every word, especially words like "not" |
| Finished on time, score close to your target | Pace and accuracy are broadly in balance | Keep the routine and review mistakes |
| Ran out of time, score decent on the questions answered | You may be spending too long on hard questions | Practise moving on and returning at the end |
| Ran out of time, score also low | Both may need work | Work on weak topics first, then timed sets |
Use the checkpoint table earlier on the page for timed practice and the free mock test timer to keep the clock in view. For the idea of using two passes through the paper, see the guide on timing a 50-question CITB mock test. Remember that practice is not an official result, and check the CITB Operatives page and the Prepare for the test page for the current details.
FAQ
How many seconds per question do I get in the CITB test?
Spread evenly, 45 minutes for 50 questions averages 54 seconds per question. That is a planning figure rather than a rule, since you are not limited per question. The CITB Operatives page gives the 50 questions and 45 minutes.
What if I am behind at the halfway point?
At 25 questions, an even pace would put you at 22 minutes 30 seconds. If you are behind, work out the pace you need for the rest using the formula above and keep reading each question carefully. Do not guess your way through, because accuracy matters for the 90% pass mark.
Does this calculator tell me if I will pass?
No. It only measures time. Passing depends on your score, and the CITB Operatives page gives the pass mark as 90%, which is at least 45 of 50. Use the pass mark calculator for that comparison, remembering that practice is not an official result.
Can I use it for a mock test with a different number of questions?
Yes, if you adjust the totals. Divide the total time in seconds by the number of questions to get the even pace, then compare your actual average with it. The calculator on this page is set up for the 50-question, 45-minute format.
