CK Quiz is independent preparation for gamified online assessments, starting with the Aon tests that P&G and many other large employers use: Switch Challenge practice with a step-by-step solver, Digit Challenge equation practice, Grid Challenge dot-memory training, PEAK Performance Assessment question formats and timed mock tests, plus figure reasoning and data interpretation. Every question is original and comes with a worked solution. Sign in for 24 hours of full access, then keep a free allowance for each type. Not affiliated with Aon, Procter & Gamble or any employer.
Each type has its own guide covering the structure underneath it, a standard procedure and the mistakes that cost most marks. The matching tool sits alongside, so you can verify as you read.
Watch pink dots light up on a blue board, then repeat their order. Practise 3, 5 or 7 positions and replay the correct sequence after submitting.
Four shapes pass through a row of boxes and come out reordered, with one box hidden for you to deduce. Underneath it is composition and inversion of permutations, and forward and backward reasoning lets you determine the unknown rule and check it against the full sequence.
Given a sequence of figures, work out the next one. The solver checks six families of transformation — fixed rotation, reflection, cyclic shift, perimeter movement, inversion, and rotation with inversion — and tells you whether the rule is unique.
Fill the blanks in an equation so it reaches a target. The skill is not calculating quickly but using remainders, divisibility and parity to cut hundreds of candidates down to a few. The solver lists every valid solution.
Read figures from tables and charts to compute growth, share or ratio. Almost every lost mark comes from the wrong denominator or a missed unit, so every question in the bank spells out where the numerator and denominator came from.
Work out the hidden four-digit code that reorders a row of symbols, with a solver that shows every step.
Fill equation blanks with distinct digits and see every valid answer, plus a fast elimination method.
Remember dot positions in order while answering symmetry questions in between.
Get used to rating, forced-choice and workplace scenario questions before the real questionnaire.
Rehearse Switch, Digit and Grid style rounds under a timer and review a per-question report.
True, False or Cannot Say passages in the style of SHL, Aon and Talent Q verbal tests, with the reasoning for every answer.
Each guide gives one fixed checking order rather than a scattering of tips. Reading it through first, so you know what each step eliminates, makes a large difference to how fast questions go.
The solvers display every intermediate result, not just the answer. Use them to confirm you have the direction right in both the forward and backward passes, and clear out systematic errors before you start drilling.
The practice bank generates questions at easy, medium and hard settings. Anything you get wrong is kept separately so you can retry just those, and every question comes with a worked explanation and, for pipeline questions, an animated walkthrough.
Questions are produced from the underlying rules on demand rather than drawn from a fixed set. You can keep practising at one difficulty. Questions may repeat, so focus on the reasoning rather than memorising an answer.
Every explanation reconstructs the full reasoning: pipeline questions animate how shapes move stage by stage, figure questions name the transformation involved, and numerical questions show the order in which to break the equation down.
Questions you get wrong are stored so you can redo only those. A mistake that keeps recurring usually means one step of your procedure has not settled yet.
The whole site runs in both languages and you can switch on any question. If you are preparing for an assessment in English, you can get used to how these questions are worded before it matters.
Registration includes a 24-hour trial of every feature without consuming credits. After the trial, each account gets 10 lifetime free uses of each solver and 10 random new questions per practice type, with full explanations. Memory training has 10 lifetime free rounds, one credit per start. Allowances do not reset daily. Buy 7-day access for continued solving and new generated questions. One-time payment, no automatic renewal.

Which companies use these testsNo. This is an independent third-party practice tool with no affiliation, partnership or endorsement from Procter & Gamble. Every question is generated from publicly discussed formats and is not real test content from any company.
The reasoning formats most often described publicly are shape-reordering questions (pipeline), figure sequences, numerical and equation reasoning, and chart-based data interpretation. This site covers those four and adds sequence-memory practice. The actual format and content of any assessment is set by the employer and can differ by year and by role.
Preparation time depends on your starting point. Try a set to measure accuracy, read the relevant guide, retry your mistakes and then introduce a timer. We do not claim a verified preparation time or pass-rate guarantee.
Yes, the pages work on phones and tablets. That said, pipeline and figure questions need you to tap cells to enter a question, which is easier on a larger screen, so a computer is better for sustained practice.
No card is required. Each account gets 10 free uses per solver, with no daily reset. Invalid inputs do not count; a completed solve counts even when no solution is found. Memory has 10 lifetime free rounds; other practice types get 10 random new questions each, and questions you have done can be retried. Existing seven-day trials are honoured until their original expiry.
