Numerical reasoning is the most common cognitive test in graduate and professional recruitment. Almost every major aptitude provider offers a numerical reasoning module — Cut-e (scales eql / lst / nmg), Saville (Numerical Analysis), Cubiks/Talogy (Logiks Numerical), Korn Ferry (Elements / Aspects Numerical), Sova, Pearson, Mercer Mettl, AMCAT. The format and timing differ, but the core skill is identical: extract relevant data from a chart or table, perform calculations, select the correct answer under time pressure.
Despite involving maths, numerical reasoning tests are not tests of mathematical ability. The maths required is GCSE-level: percentages, ratios, basic algebra, simple averages. What's actually being measured is:
"Sales increased from £4.2M to £5.7M. What's the percentage increase?" Standard formula: ((new - old) / old) × 100. The trap: percentage of vs percentage change. Read the question twice.
"If overheads grew 8% year-on-year and revenue grew 5%, what's the change in profit margin from 18% to..." These compound multiple operations. Practice doing them in pencil-on-paper to avoid skipping steps under time pressure.
Bar charts, line charts, pie charts, scatter plots, stacked area charts. The challenge isn't reading the chart — it's reading the right data point quickly. Train yourself to find values in <2 seconds.
Multi-row, multi-column tables where you must combine values from different rows or columns. Common in financial services tests. The Cut-e scales lst (lookup) test specialises in this format.
"At an exchange rate of $1 = £0.79, what's £4,250 in dollars?" Trivial maths but easy to invert under pressure. Memorise: to convert £ to $, divide by 0.79 (or multiply by 1.27).
"Year 1 revenue was £100. It grew 10% in year 2 and dropped 8% in year 3. What's year 3 revenue?" Common trap: 100 + 10% - 8% does NOT equal 100 + 2%. The correct sequence: 100 × 1.10 = 110; 110 × 0.92 = 101.2.

Numerical reasoning is where AI solvers genuinely outperform human candidates under time pressure — and it's where TestSolve performs best. Our 94% accuracy on numerical questions reflects three engineering choices:
Vision-based extraction. Where most "test prep" tools require you to type the question, TestSolve uses GPT-5.5 vision to read the chart, table, or screenshot directly. This means complex multi-axis charts and blurred PDF data are handled accurately.
Numerical option matching. After computing a candidate answer, TestSolve checks against the listed options with a tolerance band, accounting for rounding. If your calculated answer is £127,000 and the options are £125K / £127K / £130K / £135K, the matcher correctly picks £127K rather than rounding inconsistently.
Final-number extraction fallback. When the AI's reasoning produces a single explicit answer in the explanation but doesn't snap to an option ID, the extractor pulls the number from the explanation text and matches it. This catches the edge cases where Claude or GPT produces correct working but ambiguous output.
For numerical reasoning specifically, ReasonEra and similar inductive-only competitors offer no help. TestSolve is the only AI solver that handles full-spectrum numerical reasoning across every major provider.

Numerical reasoning scores are reported as a percentile against a comparison group — usually graduates, working professionals, or a role-specific norm — rather than a fixed pass mark. A 50th-60th percentile result is a common minimum for general graduate screening, while competitive finance, consulting, and quantitative analyst schemes often require the 70th-80th percentile or higher. Because numerical reasoning is one of the most heavily weighted categories in many combined assessment batteries (correlating strongly with on-the-job analytical performance), a below-target numerical score sometimes can't be fully offset by strength in verbal or abstract reasoning, depending on how the specific employer's scoring model combines subtests.
A skill that separates fast, accurate candidates from slower ones is recognising when estimation is not just acceptable but strictly faster and just as reliable as exact calculation. When answer options are spread widely apart (say, £120K, £150K, £180K, £210K), rounding the underlying figures generously and estimating gets you to the correct option just as reliably as painstaking exact arithmetic, in a fraction of the time. Reserve full precision for cases where answer options are genuinely close together (£148K vs £152K vs £156K), where estimation alone can't reliably distinguish between them. Building the judgment to recognise which situation you're in — at a glance, before committing to a calculation approach — is itself a trainable skill worth deliberately practising, not just a byproduct of doing more questions.
1. Identify your specific test. SHL prep is different from Cut-e prep. Don't blanket-practice "numerical reasoning" — find out which test your employer uses and target practice accordingly.
2. Drill mental arithmetic. Most calculator-allowed tests still reward fast mental arithmetic for elimination and estimation. Practice 50% / 25% / 10% calculations until automatic.
3. Master one chart type per session. Spend a session on bar charts, another on line graphs, another on multi-axis charts. Mixed practice from day 1 builds slower competence.
4. Time everything. Untimed practice teaches you to compute correctly. Timed practice teaches you to compute fast. Both matter, but timed matters more for the actual test.
5. Use TestSolve in mock sessions. Run TestSolve through 1-2 full timed practice tests. The 4-6 second answer delivery means you can spot-check your own answers and learn where you systematically go wrong.
Numerical reasoning on Numerical Reasoning tests is almost always table-based: two or three small tables of financial, sales, or operational data, followed by a question that requires a multi-step calculation and a unit conversion.
Q. A retail chain sells three product lines. Units sold last quarter were 660 (Line A), 1,140 (Line B) and 310 (Line C). Average selling price was £1.00, £1.00 and £1.00 respectively. Total revenue to the nearest £ was:
A) £1,780 B) £1,950 C) £2,048 D) £2,110
A. Sum the units: 660 + 1,140 + 310 = 2,110. Answer: D.
The actual Numerical Reasoning question adds distractors: prices in pence rather than pounds, mixed currencies, unit ambiguity (per pack vs per item). Candidates who rush the unit check pick C or B despite nailing the arithmetic.
A typical standalone numerical reasoning test gives 16 questions in 20 minutes — about 75 seconds per question. That sounds generous but each question has 3–5 numbers to read, a calculation (often multi-step), and a unit conversion.
If you're past 90 seconds and still unsure, flag and move on — you can't recover several lost minutes from one stubborn question.
