The Aon numerical reasoning test, often still called the cut-e scales numerical test, is one of the most distinctive numerical assessment formats candidates face. It is not just a calculator-style arithmetic exam. It is a fast, data-driven, statement-evaluation test where you must find relevant information in charts, tables or tabs and decide whether a statement is true, false or cannot say.
This format creates a very specific kind of pressure. You may understand percentages, ratios and comparisons perfectly well in normal conditions, but still lose time because the data is split across several tabs, the statement is worded in a precise way, and the timer forces you to decide quickly. That is why a dedicated Aon numerical reasoning page is valuable: candidates searching this term are not only looking for generic numerical practice. They are trying to understand the Aon/cut-e format.
Aon Numerical Reasoning at a glance
- Module name: Aon scales numerical (cut-e legacy naming still in widespread use as of 2026).
- Length: 37 tasks in 12 minutes — roughly 19 seconds per task. Among the fastest numerical formats in the market.
- Format: tab-based — data is split across 2 to 4 information tabs. Candidates must find the relevant tab before evaluating each statement.
- Answer options: true / false / cannot say. Roughly one third of correct answers are typically "cannot say" — the most common error is treating "not in the data" as "false".
- Used by: Deloitte, Unilever, Vodafone, Allianz, Lufthansa, and roughly 700 SHL-and-Aon-licensed employers across Europe and Asia. Typical graduate cutoff: 50th percentile against the Aon Graduate norm group.
What is the Aon numerical reasoning test?
Aon's public candidate preparation materials describe numerical reasoning as a 12-minute assessment with 37 tasks, where candidates determine the truth and accuracy of a statement based on numerical data provided. The format is widely known as scales numerical in the cut-e test family. Third-party preparation sources describe the same format as a tab-based numerical reasoning task where each statement is evaluated against available data.
The test usually presents information in multiple tabs or panels. These may include revenue, costs, regional growth, product categories, market share, headcount or other business-style data. The candidate reads one statement and decides whether it is true, false or cannot say based only on the available data. The challenge is not only calculation. It is deciding which tab matters, extracting the correct figures, and resisting the urge to infer beyond the data.
This is different from many standard numerical reasoning tests. A typical SHL-style numerical question may show a chart and ask you to compute one value from several answer options. Aon scales numerical often asks you to judge a statement. That means your workflow must be evidence-led: find the relevant tab, identify the exact data, perform the comparison and then map the result to true, false or cannot say.
Why Aon numerical reasoning feels difficult
The first difficulty is time. Thirty-seven tasks in twelve minutes means you have roughly nineteen seconds per task if you attempted all of them evenly. In practice, some questions will take longer, and some should be answered quickly. That is why candidates must build a fast pattern: identify the claim, identify the tab, calculate only what matters, and move.
The second difficulty is tab navigation. The correct answer may depend on a data tab that is not immediately visible. Candidates often waste time reading all tabs in order rather than using the statement as a search instruction. If the statement mentions "research and development costs," start with the R&D or costs tab. If it mentions "regional growth," do not start with total revenue unless the wording specifically requires it.
The third difficulty is wording. Aon numerical statements often contain comparisons like "greater than," "less than," "combined," "at least," "more than twice," "percentage increase," "share of total," or "higher than in any other year." Each phrase changes the calculation. A small wording mistake can flip true to false.
The fourth difficulty is cannot say. Candidates sometimes assume that if they cannot prove a statement, the answer must be false. That is wrong. False requires contradiction. Cannot say means the available numerical data is insufficient. If the statement asks about profit but the tabs only show revenue and headcount, you may not be able to decide unless costs or margins are visible.
Common question patterns
One common pattern is direct comparison. The statement may say that sales in Year 5 were higher than sales in Year 4. You locate the relevant sales tab and compare the two numbers. This is the simplest pattern.
A second pattern is combined comparison. The statement may compare one year against two years combined, one region against several regions, or one product line against the total of others. This is where candidates often fail because they compare against only one number instead of the combined figure.
A third pattern is percentage change. The statement may say that revenue increased by more than 15 percent. You need the previous value and the new value, then calculate the percentage change as difference divided by the original value. Confusing percentage points and percent change is a common trap.
A fourth pattern is share of total. The statement may say that a division accounted for more than one-third of total sales. You need the division value and the total, then calculate or estimate the share. Often an estimate is enough if the numbers are far apart, but precise calculation helps when values are close.
A fifth pattern is missing information. The statement may refer to profit, customer satisfaction, market share or forecast growth when the visible tabs do not provide the needed data. If the data is not there, the correct answer may be cannot say.
Example-style walkthrough
Suppose the question shows a business data set with several tabs: Revenue, Costs, R&D, Regional Growth and Stocks. The statement says: "Costs in Year 5 were greater than the combined costs of Year 4 and Year 6."
A weak approach is to scan all tabs and start calculating from the first chart you see. A better approach starts with the word "costs." That tells you the relevant tab is the costs tab. The statement then asks for Year 5 compared with Year 4 plus Year 6. If the costs are Year 4 = 20,050, Year 5 = 47,607 and Year 6 = 29,870, the combined Year 4 and Year 6 figure is 49,920. Year 5 costs of 47,607 are less than 49,920. Therefore, the statement is false.
Notice what made the question hard. The calculation itself was simple addition and comparison. The challenge was understanding that the statement compared Year 5 against a combined value, not against either Year 4 or Year 6 individually. A candidate who rushed might see that Year 5 is greater than Year 4 and incorrectly answer true. The correct workflow prevents that mistake.
How TestSolve helps with Aon numerical practice
TestSolve should be positioned as a practice reasoning assistant for this exact workflow. When a candidate captures an Aon-style numerical practice question, TestSolve can read the statement, identify the relevant data labels, extract visible numbers, build the calculation, and explain whether the statement is true, false or cannot say.
The value is not only the answer. The value is the reasoning trace. A good walkthrough should say: relevant tab = costs; relevant values = Year 4, Year 5, Year 6; required operation = Year 4 plus Year 6; comparison = Year 5 against combined value; conclusion = false. That turns a failed practice attempt into a reusable method.
For candidates who are bad at numerical reasoning under time pressure, this is especially useful. They may not need a full course on arithmetic. They may need help seeing how to start. TestSolve can make the first step explicit: what is being asked, what data matters, what calculation is needed, and which answer follows.
Preparation strategy
Practise in three passes. First, practise untimed to learn the format. Read the statement, choose the tab, do the calculation and write down why the answer is true, false or cannot say. Second, practise timed but allow yourself to review mistakes carefully afterward. Third, practise speed triage: identify which questions are quick wins and which ones should be answered with controlled estimation or skipped.
Build a personal error log. Categories might include wrong tab, wrong comparison, forgot combined value, percent-change mistake, confused false with cannot say, and over-calculated. This is where TestSolve output can help: after each practice question, compare its explanation to your own thought process and record the mistake type.
Also practise mental arithmetic and estimation. Some Aon numerical formats may not allow a calculator, and even when a calculator is available, speed matters. You should be comfortable with percentage increases, ratios, averages, differences, sums and rough comparisons.
