Sat an online assessment for a job application? Assessment Ready is practice for the cut-e / Aon test range — the aptitude tests employers use to shortlist candidates before interview. Every test is rebuilt to mirror the real thing: the same formats, the same time pressure, the same answer mechanics. Practise until the format stops costing you marks, so on the day you are only being tested on what you actually know. WHAT'S INSIDE — 16 TESTS THE SMARTPREDICT CHALLENGES (5) Aon's gamified series, used at the front of graduate and volume-hiring schemes. • Deductive Reasoning (switchChallenge) — find the code that reorders the row • Deductive Reasoning (gapChallenge) — fill the gap so no shape repeats • Working Memory (gridChallenge) • Complex Planning (motionChallenge) • Numerical Comprehension (digitChallenge) THE SCALES RANGE (11) The classic timed ability tests, used across graduate, commercial and technical roles. • Numerical Reasoning — read tables and charts against the clock • Verbal Reasoning — true / false / cannot say on business passages • Logical Reasoning, Inductive Reasoning and Inductive Logic • Abstract Logic • Spatial Reasoning — fold the net into the cube • Language Skills — business grammar, spelling and vocabulary • Concentration — speeded accuracy under pressure • Mechanical & Technical Comprehension — gears, pulleys, springs, torque • Understanding of Basic Instructions — read the tabs, judge each statement WHY IT WORKS • Authentic - tuned to the real timing, controls and scoring, not a generic quiz • Adaptive - several tests get harder as you answer correctly, like the real ones • Instant scoring - see exactly where you lost marks, question by question • Answer review on the written tests - go back through what you got wrong • Global leaderboards — see how you rank against other candidates • Progress tracking - your accuracy and speed on every test over time • Community - prepare alongside other candidates on our Discord • Four languages - English, German, French and Spanish, with the word-based tests written natively in each rather than machine-translated • Practise anywhere - short sessions that fit around your day WHO IT'S FOR Anyone sitting a cut-e / Aon (Aon Assessment Solutions) online test as part of a job application - graduate schemes, apprenticeships, and commercial, technical, finance, consulting and volume-hiring roles.
