Numerical reasoning practice test: a timed review method
Read units first, estimate the answer, calculate carefully, and classify each error before trying another short timed set.
Before you start
This guide is for UK graduate-job applicants preparing for a timed numerical reasoning assessment. Bring scrap paper, a timer and the calculator permitted by your practice set. Check the employer invitation before the live assessment because timing, navigation and allowed tools vary.

What you'll learn
- Read labels and units before calculating.
- Estimate the likely size of an answer.
- Complete a short timed set using its stated rules.
- Classify each miss before practising again.
Why this method works
Numerical reasoning combines data interpretation with calculation. A correct formula does not help if you select the wrong row, miss a unit or use the wrong comparison.
A short timed set practises the whole decision: read, scan, estimate, calculate and check. Labelling each miss as reading, method, arithmetic or pacing tells you what to change next.
Session script
- 00:00–03:00: Review common table labels, currencies, percentages and multipliers.
- 03:00–19:00: Choose a published 12-question or 24-question Practice Hub set. Each has a 16-minute practice clock.
- 19:00–27:00: Rework each miss without the answer visible and label the error type.
- 27:00–30:00: Write one rule for the next set, such as “check the denominator”.
Worked examples
Example 1: Percentage change
Revenue rises from £1.2 million to £1.5 million. Use the original value as the base: the increase is £0.3 million, and £0.3 million divided by £1.2 million is 25%.
Example 2: Reading units
A table labelled “£000s” shows 4,500. The value is £4,500,000. Record this as a reading error if the arithmetic was correct but the multiplier was missed.
In tests and exams
Formats differ across employers and assessment providers. Use the invitation and examples to confirm the clock, calculator rule, navigation and whether you may revisit unanswered questions.
Common tasks include percentage change, ratios, rates, averages, conversions and comparisons across tables or charts. Practise reading the question and units before touching the calculator.
Practice
- Warm-up: Convert 0.375 to a fraction.
- Warm-up: Interpret 2,750 in a table labelled “£000s”.
- Standard: Find the percentage increase from 80 to 100.
- Standard: £45,000 is 15% of a budget. Find the total.
- Challenge: Compare growth from 200 to 280 with growth from 1,500 to 1,950.
Answers
- 0.375 = 3/8.
- £2,750,000.
- (100 − 80) ÷ 80 × 100 = 25%.
- £45,000 ÷ 0.15 = £300,000.
- The first grows by 40%; the second by 30%; the difference is 10 percentage points.
Common traps
- Using the new value instead of the original base.
- Missing a unit, note or chart multiplier.
- Calculating before estimating the likely size.
- Applying a navigation rule that the assessment does not allow.
Quick recap
- Read the question, labels, units and notes.
- Estimate before entering values.
- Use the clock supplied with the set.
- Classify each miss before the next short set.
