ENAC Law and Anti-Law
IntellectualPSY1Three numbers, words or figures obey a hidden law, and three don't. Under them are 8 propositions: tick every one that obeys the law. Numbers, words and figures are mixed through the run. The exam format is 35 boards in 30 minutes, and you're free to move between boards and change your ticks until you hand in.
Overview
Run the same checks on every board, in the same order. Count first (digits, letters, elements), then look at positions (the first, the last, the second), then at arithmetic (sums, multiples, squares). The anti-law saves you time: hold each idea up against its three examples before you test a single proposition. You get about 51 seconds a board, so there's no time to stare at one that won't open. Flag it, move on, and come back once the others are done.
Assessments
Part of the Air France Cadets selection at ENAC (PSY1) battery as “Efficience générale”.
Three examples obeying a hidden law, three breaking it, and a set of propositions to tick, with boards of numbers, words and figures mixed under one clock for the whole test and free movement between them. The group that breaks the law is not a second law: it is there to rule out the readings that fit the first three by accident. On most boards the two groups separate cleanly, so the law is hard to find rather than ambiguous; when two laws both fit all six, take the one that lets you tick the most.

Law, anti-law and eight propositions
- The law: three numbers, words or figures that obey one hidden rule.
- The anti-law: three that don’t. If a rule fits the first three but also fits one of these, it isn’t the law.
- The propositions: tick every one that obeys the law, and none that breaks it. At least one obeys, never all eight.
- Two laws fit? The answer is the one that ticks more propositions.

Game Phases
Read the Law Side
Find what all three law examples have in common. Count the digits, letters or elements before anything else.
Test the Anti-law
If one of the three anti-law examples has that feature too, it isn't the law.
Tick Every Match
Test all 8 propositions against the law word for word, and tick each one that obeys.
Keep Moving
If a board won't open, flag it and come back to it at the end.
More Practice
Abstract Reasoning
8 exercisesNon-Verbal Reasoning
Spot the rule in a set of abstract figures — pick the odd one out, the option that completes the pattern, or the true rotation of a figure. Tests non-verbal, fluid reasoning under time pressure.
Figural Analogies
Work out how the first shape becomes the second, then apply the same transformation to the third shape and pick the figure that completes the analogy. Tests non-verbal, abstract inductive reasoning under time pressure.
Rule Application
Hold a small rule-set in mind and apply it to a fast stream of coloured symbols — press the response each rule dictates before the window closes.
Matrix Transformations
Discover the hidden rule linking two example symbol grids, then mark exactly the two of four candidates that follow it — the real cut-e (Aon) scales clx screen, in its official 6-minute length. A classic pair-transformation mode remains as the practice variant.
Odd One Out
Nine abstract objects share a hidden rule — spot the one that breaks it, fast. Replicates the cut-e (Aon) scales ix inductive reasoning test.
Grid Classification
Six example tables, two hidden classes — deduce the rule that separates them and assign new tables to the right class. Adapted from the cut-e (Aon) scales cls format, including an Assessment Format mode that mirrors the real screen: four unmarked tables per item, 12 items in 12 minutes.
Switch Challenge
Deduce which numbered operator — a digit code that reorders a row of symbols — turns the top row into the bottom row. Replicates the cut-e (Aon) switchChallenge from the smartPredict battery.
ENAC Figure Matrices
A 3 × 3 matrix of figures with the bottom-right square missing, and 8 options to complete it. The rules run along the rows, down the columns and across the diagonals, and a board often has two or three at once. The exam format is 30 boards in 30 minutes, and you can move between boards and change your answers until you hand in.
