How long can you spend on each question?

Divide the time by the questions and you have your average. The number is only useful if you check it while you test, so the calculator also gives checkpoints: where you should be a quarter, half and three quarters of the way through.

• Keep time for review. Setting aside 5 to 15 percent lets you go back to flagged questions.
• Averages are not limits. Some questions take 30 seconds and some take three minutes. Move on from the ones that stall you.
• Practise with a clock. Do timed practice sets at this pace before test day so it feels normal.
• Check the official rules. Your exam may have timed sections, breaks or a different number of scored questions. Use the numbers from the exam owner.
