Logical reasoning tests measure how you spot patterns and apply rules under time pressure. They use shapes, sequences, and diagrams — no specialist knowledge required. The fastest improvement comes from learning to classify which pattern family you are looking at before you try to solve.

TL;DRthe 30-second version
  • Logical reasoning is mostly pattern-family recognition under a timer.
  • Classify before solving: movement, count, rotation, shading, symmetry or combination.
  • One counter-example should kill a hypothesis immediately.
  • Review should identify the missed family, not just the missed answer.

Logical reasoning improves fastest when you drill one pattern family at a time. Start logical practice

What to focus on first

Focus areaWhy it mattersBest drill
Pattern familyThe family tells you which rule to test first.Name the family before solving.
Hypothesis testingA rule must explain every frame.Test one rule across the whole sequence.
Two-rule itemsHard questions often combine position and count or shading.Track each changing feature separately.
Skip disciplineSome items are time traps.Move on after the first dead hypothesis if timing is tight.

Common traps

  • Committing too early. The first visible pattern may explain only part of the sequence.
  • Holding two hypotheses at once. Test one, then discard or keep it.
  • Overlooking unchanged features. Static elements can be anchors for movement or rotation.

How to practise from here

Do two passes through a set. First pass: write only the pattern family. Second pass: solve. This separates recognition from execution and makes review much cleaner.

forge trap note
The point is not to read more advice. Take one timed set, review the exact failure pattern, then repeat the smallest drill that fixes it.

Logical reasoning tests cover multiple formats — diagrammatic patterns, sequences, deduction puzzles. In pre-employment contexts, these tests are used because they do not require specialist knowledge: they test how you infer rules and apply them consistently under a clock. Start with pattern families if you miss visual rules, use abstract reasoning if your invite names shapes or matrices, and move to SHL inductive reasoning when the provider is SHL.

The core method: observe → hypothesise → test

  1. Observe changes across steps (shape, count, rotation, shading, position).
  2. Hypothesise one rule.
  3. Test it across all items.
  4. Only then commit.
The most expensive mistake
Committing to a rule before you have tested it across every item in the sequence. One counter-example should send you back to step 2 immediately.

High-frequency pattern families

  • Rotation (fixed degrees, alternating directions).
  • Count changes (number of sides, objects, intersections).
  • Colour inversion (swap filled / unfilled).
  • Movement (clockwise shifts, alternating positions).
  • Combination rules (two small rules at once).

How timing actually improves

You improve timing by two things, in this order:

  1. Recognising the pattern family faster.
  2. Avoiding dead-end hypotheses earlier.

Trying to “think faster” without those two is how people panic and lock in wrong answers.

Provider formats to recognise

SHL often separates inductive and deductive reasoning, while AON may label abstract tasks as scales ix, cls or inductive logical. The practice route changes with that label. Inductive tests usually ask you to infer a hidden visual rule; deductive tests give rules or premises and ask what must follow. If you are unsure, use the SHL invite decoder or the AON invite decoder before doing broad logic drills.

Example
A sequence shows a triangle rotating 90° clockwise each step, while a dot moves one corner counter-clockwise. Which option is next?

Approach: track the triangle rotation separately from the dot movement; do not treat them as one rule. Decomposing a combined rule into two simple rules is usually the difference between solving in 20 seconds and staring for 90.

The 5-second classify rule
Before you try any rule, spend five seconds classifying which family you are looking at. That single habit cuts your average solve time more than any other change.

How forge fits in

Logical reasoning is where “tagged questions plus streak drills” makes the most sense. You want repetition until pattern families become automatic — the goal is to feel bored, not challenged, by the end of a drill session.

In review, write the missed family beside every wrong answer. A note like “rotation plus count” is more useful than “got it wrong” because it tells you exactly what to drill next.

Source notes

forge checks logical-reasoning advice against official provider material, including SHL’s cognitive assessments overview and Aon’s online assessment preparation page. The underlying skill is stable, but provider interfaces differ.

How is logical reasoning different from IQ tests?+

In practice, there is heavy overlap. Employer logical reasoning tests tend to use diagrammatic or inductive formats and are designed to be answerable without specialist maths knowledge.

What is the single biggest improvement I can make?+

Learn to classify the pattern family in the first five seconds. Everything else follows from that — you stop wasting time on hypotheses that do not fit the family.

Should I memorise rules?+

No. You should memorise families. Rules within a family vary, but the families themselves are small and repeat.
