Aon assessment practice: Switch, Digit and Grid challenges and cut-e tests
Written and maintained by CKAutoFlow
Aon, which bought the test publisher cut-e in 2017, supplies online assessments to many large employers. Its best-known format is smartPredict: short gamified challenges such as Switch, Digit and Grid. This guide explains each one, which employers are reported to use them, and where to practise each skill for free.
Scope at a glance
Aon (cut-e) assessments include gamified challenges (Switch, Digit, Grid, Motion) and classic scales tests (verbal, numerical, inductive). Identify the task in your invitation, then practise that skill.
What is in an Aon assessment?
Aon’s gamified smartPredict assessment is made of short challenges, each measuring one ability. Prep providers commonly list four: Switch (deductive logic), Digit (numerical), Grid (working memory) and Motion (planning). Employers can also send classic cut-e scales tests, such as scales verbal (true/false/cannot say), scales numerical (tables and charts) and scales ix (inductive patterns), and a personality questionnaire.
- Switch Challenge (scales sx): find the four-digit code that reorders a row of symbols. Practise with the step-by-step Switch solver.
- Digit Challenge: fill equation blanks with distinct digits. Practise with the Digit solver and equation drills.
- Grid Challenge: remember dot positions while answering symmetry questions. Practise with Grid Challenge training.
- Verbal (scales verbal): decide whether statements are true, false or cannot say. Practise with free verbal reasoning passages.
- Numerical (scales numerical): read tables and charts. Practise with data interpretation questions.
Which employers use Aon assessments?
Procter & Gamble describes Switch-, Digit- and Grid-style games in its own Interactive Assessment guidance. Prep providers also list employers such as Deloitte, KPMG, EY, Morgan Stanley, UBS, Johnson & Johnson, Capgemini, Vodafone and Siemens among Aon or cut-e users for some roles. Those lists are not confirmed by the employers and change by country, role and year, so always check your invitation for the provider name and task list.
Original example: a one-box Switch question
Input ● ▲ ■ ◆ becomes ■ ● ◆ ▲. Which code?
- New slot 1 is ■, which was in old position 3.
- New slot 2 is ●, from old position 1. New slot 3 is ◆, from old position 4. New slot 4 is ▲, from old position 2.
- The code is 3142. Check by applying it to the input before answering.
How to prepare in a week
- Days 1–2: learn the method for each challenge without a timer until you are accurate.
- Days 3–5: practise each challenge with a timer and note which one costs you most time.
- Days 6–7: take a full timed mock test, then rest before the real assessment. Results here do not predict an employer’s pass mark.
Put the method into practice
After the 24-hour full-feature trial, get 10 random new questions per practice type (10 lifetime memory rounds) and use each solver 10 times for free, with no daily reset. Paid access unlocks new generated questions and continued solving with 7-day access.
