You get a 4×4 or 5×5 grid of symbols. Some cells are filled, some are empty, and exactly one holds a question mark. There is a single rule: every symbol appears once in each row and once in each column. Work out which symbol belongs in the question mark and pick it from the strip below the grid — one click and it is final, with no confirm and no undo. Six minutes, and a new puzzle after every answer.
The rule fits in a sentence, and everything else follows from it. The part most candidates get wrong is the target: you are not solving the grid, you are solving one cell. Only the question mark is guaranteed to have a single answer — some of the other empty cells are genuinely ambiguous. The five walkthroughs below play themselves, in the order you should learn them.
The teaching view. The autopilot does not stop at the question mark: it fills the whole grid, so you can watch every symbol land exactly once in each row and each column. The card counts the cells as it goes, and once the grid is complete it says that only one symbol is still missing from the ? — then answers.
The test is not a knowledge check and not a pure speed drill. It measures whether you can take the constraints in front of you and reach the one answer they force — and whether you can keep doing that while the clock runs. The score is built from how many you get right, with a penalty that grows as accuracy falls.
From the symbols already on the board there is exactly one that can sit in the question mark. You are not judging, estimating or recalling — you are eliminating.
The habit is what is measured: two complete reads before the hand moves. Most wrong answers are a skipped scan, not a failed deduction.
There is no per-puzzle limit, so a stall costs only time. Past about forty-five seconds you have left your procedure — restart it rather than stare.
Six minutes is short but dense. The report compares your first third with your last third; a large gap is stamina, not technique.
Every Deductive Logical Reasoning session you finish is broken down automatically. See more than the right–wrong ratio: where you slowed down, how your solve time moved across the session, and whether you held your accuracy as the levels got harder.
Every answer’s duration with a five-answer moving average, plus your median and fastest solve.
Right–wrong ratio plus every mistake classified: row conflict, column conflict, both, or a multi-step chain error.
How accuracy and timing shift between 4×4 and 5×5, which steps you reached, and whether your last third sags.
A progress chart across sessions, the consistency of your answer times, your percentile and a personalised study suggestion.

It is the Aon test listed as "scales lst" in the assessment battery and named gapChallenge inside the product. You see a 4x4 or 5x5 grid of symbols in which every symbol appears exactly once in each row and each column, with exactly one cell holding a question mark. You pick the symbol that belongs in that cell from the strip under the grid. The session lasts six minutes and the number of puzzles is not capped.
Candidates preparing for the Wizz Air Pilot Academy selection process, and anyone who wants to practise Aon-style deductive logical reasoning under real time pressure. No prior knowledge is needed: the rule is a single sentence and the symbols carry no meaning.
Yes. The player and the walkthroughs on this page load the same module you get after purchase, straight from hub.cadetpro.com. The walkthroughs run themselves so you can watch the method before you play; the free EASY and MEDIUM modes are open without buying anything.
Any modern browser on desktop, tablet or phone. Answering is a single tap or click on the answer strip, so a mouse is not required.
EASY (3 minutes) and MEDIUM (4 minutes) are free and give feedback while you play; they are for learning the rule and the interface. HARD (6 minutes, 5x5 only) trains multi-step chains. EXAM (6 minutes) removes all feedback and reproduces exam conditions — only completed EXAM sessions count towards your score, ranking and badges.
PRO access opens the HARD and EXAM modes and the eleven advanced sections of the performance report. Access runs for the period you choose — 30, 90 or 365 days — and renews automatically for the same period unless you cancel.
No. CADETPRO is an independent preparation platform and has no affiliation with, endorsement from or partnership with Wizz Air or Aon. The module reproduces the publicly described format of the test so you can practise it; it is not the assessment itself, and no result here guarantees any outcome in a real selection process.
