Logical reasoning test practice

Logical thinking in these batteries means finding a rule from examples and applying it consistently — not verbal logic puzzles. Some items are inductive (work out the hidden rule), some are deductive (eliminate until one answer survives).

Rules are the substance of the job. A controller applies a large set of them continuously and cannot pause to look them up, so selection tests how quickly you can absorb an unfamiliar rule and use it correctly.

Where the marks go

On elimination items, build two separate lists — what the row rules out, what the column rules out — and intersect them. It is consistently faster than scanning, and the harder items are built to reward it.

Logical Reasoning — Grid Rules

Two example grids are linked by a hidden rule — the grid is rotated and each symbol swapped for another. You work out the rule, then pick the two grids from four that are linked by the SAME rule.

Rule-finding under time pressure is what logical thinking means in these batteries. It is visual rather than verbal, which is why it is shown rather than written out here — a static description of a grid transformation is not a sample of it.

Rule Discovery

Diamond-shaped grids are tagged either yellow or blue, each colour standing for one of two hidden rules. You work both rules out from the tagged examples, then decide which colour a new grid belongs to. Right answers flash green, wrong ones red.

Two rules rather than one is what makes it hard: you cannot simply find a pattern, you have to find the boundary between two of them. It is a visual task, so it is described here rather than written out — a static rendering of a grid classification is not a sample of it.

Deductive Reasoning

Deduction by elimination. Each of six shapes appears exactly once in every row and once in every column — a Sudoku with shapes instead of digits.

One cell holds a ?. Its ROW already contains the circle, hexagon, square and star. Its COLUMN already contains the circle, hexagon, square and triangle. Which shape goes in the ?
