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.

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.

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.

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.

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.
