Graduate Numerical Reasoning Test Practice

Read the data before calculating

Identify the requested output, period, category and unit. Estimate the likely size of the answer before using a formula. This catches a surprising number of errors caused by a wrong row, wrong denominator or misplaced decimal.

Work a percentage example

This table and question are original. They do not imitate a provider’s protected dataset, interface or scoring.

Use an accuracy review that improves pace

Label each mistake by its earliest cause: data selection, base value, formula, arithmetic, units, rounding, answer selection or time management. Repair that cause on a fresh question before repeating a full timed set.

Once the method is stable, shorten the working without hiding essential steps. Timing every session too early can reinforce fast mistakes. Alternate focused drills with mixed sets so you learn both the method and when to use it.

Practise one calculation family at a time

Start with the error that costs you the most accuracy, then test the repair using different data rather than a memorised item.

Practise the calculations that appear in data questions

Common operations include percentages, percentage change, ratios, rates, averages and unit conversions. Learn what each operation means rather than memorising a list of formulas. For a ratio, identify the order of the categories; for an average, confirm what belongs in the total and count; for a rate, preserve the time or output unit.

Charts add a visual-reading step. Check the axis, scale, legend, baseline and whether values are totals or percentages. A truncated axis can make a small change look dramatic, while a stacked chart can require subtraction before comparison.

Turn errors into focused drills

If you repeatedly choose the wrong base for percentage change, practise identifying the original value before calculating. If arithmetic is accurate but slow, rehearse fraction-percentage equivalents and estimation. If table selection is the problem, answer the question in words and point to the required row and column before touching the calculator.

Use a short mixed set after each drill. The mixed set tests whether you can recognise when the repaired method applies. Keep all practice data fictional or public; do not reproduce confidential employer information.

How should you round an answer?

Follow the instruction and answer options. Keep extra precision during working, then round once at the end unless the task says otherwise.

What if your answer is not among the options?

Check the requested unit, denominator, period and rounding. Then confirm that you entered the value correctly. Do not force the nearest option without understanding the difference.

How can you improve speed safely?

Reduce avoidable rereading, use estimation to reject impossible options and organise working consistently. Do not skip the unit or base check that protects accuracy.

Use a compact numerical review sheet

For every missed question, record the required output, selected data, formula, working, unit and final check. Highlight the first field that became incorrect. This makes it clear whether you need data-reading practice, concept review or faster arithmetic.

Build a small reference list of relationships you understand, such as percentage change, weighted average and rate. Do not use it during a live assessment unless notes are explicitly permitted. Its purpose is to clarify practice, not bypass test rules.

How many decimal places should you keep?

Keep enough precision to avoid changing the answer, then follow the requested rounding. If options are far apart, estimation can confirm the correct range.

What if numbers make you anxious?

Reduce the task to labels, base, operation and unit. Short untimed drills with full explanations can rebuild control before timed work.
