Checking accuracy
Practise comparing letters and numbers quickly and accurately. Select the exact copy of a reference code from five similar alternatives.
Every drill and full-length test has 10 questions.
Every question type, explained
The test uses one question format. Here's how it works, what it really measures and where candidates lose points. Every demo is a working question from our practice set — try it.
Compare the reference code with five alternatives and select the one that matches exactly.

Know what is being assessed
Numerical reasoning is about making sense of information. You need to identify relevant figures, recognise the relationship between them and use the right calculation. In an interactive test, you also need to translate that result into the requested chart or response.
Practise reading units, time periods and labels carefully. A correct calculation can still lead to a wrong answer if you use the wrong baseline or confuse a percentage with a percentage-point change.
Confirm the exact test name, deadline, calculator rules and any adjustments agreed with the employer.
Refresh percentage changes, proportions, ratios and averages. Review why an answer is correct rather than memorising it.
Once the format feels familiar, rehearse under the conditions given in your invitation and look for where you lose time.
Use a stable connection and a quiet space. Read the official instructions and complete any introductory examples carefully.
No. They are separate tests. Numerical Ability uses a multiple-choice format, while this page focuses on checking accuracy. Use the exact name in your invitation to choose your preparation.
We cannot know your employer's question set. The goal is to prepare for the skills and interaction types, not to provide confidential assessment questions.
The overview above is provisional and may differ from your assessment. Your employer's invitation and the official test instructions are the source of truth for the question count and time limit.
