How to Prepare for Numerical Reasoning Questions

Numerical practice can involve reading tables or charts and applying percentages, ratios and arithmetic. This guide offers an original worked example and a method to try. It does not establish employer requirements or a validated ability score. Check your assessment invitation for the actual tasks, timing and permitted tools.

The 5-step method

  1. Read the question before scanning the data. Identify what must be calculated or compared.
  2. Use an estimate to check a calculation. For a True/False/Cannot Say item, an estimate alone may not settle the answer.
  3. Write the calculation down, and use a calculator only when your assessment instructions permit it.
  4. Check units and time periods, such as thousands versus millions or quarterly versus annual figures.
  5. Read the navigation rules. Skip, flag or return to an item only if that assessment permits it.

Worked example

Revenue was £4.2M in 2023 and £5.04M in 2024. What was the percentage increase? Change = 5.04 − 4.2 = 0.84. Then 0.84 ÷ 4.2 = 0.20 = 20%. Notice 0.84 ÷ 4.2 simplifies to 1/5 — you never needed the calculator.

Tips

  • Try the worked example without a timer first; add timed practice when it is relevant to your actual task.
  • Keep a mistakes log with the calculation or assumption behind each miss.
  • Compare the answer with a rough estimate and check that it uses the requested unit.
  • Check your device and any permitted tools before the assessment.
  • Choose a manageable preparation schedule and allow time for rest.

Frequently asked questions

Are numerical reasoning tests hard?

The worked example here uses subtraction, division and percentage change. Your own assessment may use different content; read its instructions rather than inferring the required level from this example.

Can I use a calculator?

Check your invitation and provider instructions. This guide does not establish whether your assessment allows a calculator or provides one on screen.

How long is a numerical reasoning test?

Use the time limit stated in your own invitation. JTP practice uses its displayed settings and limits, and its timed numerical run requires sign-in.

What score do I need to pass?

This guide and JTP practice results do not establish an employer pass mark. Review the calculations and consult the assessment instructions for any stated scoring requirements.
