Thinking Skills

Thinking Skills: The Section That Trips Up Strong Students

What the Thinking Skills section tests in the NSW OC and Selective tests, the question styles to expect, why strong school students often underperform, and how to build the skill gradually.

Thinking Skills is the section parents least expect — and the one that most often surprises a confident student. It doesn’t test anything taught at school. Instead it measures how a child reasons, which is why a high achiever can sit down to their first practice set and find it genuinely hard.

Where it appears

OC test
30 questions · 30 minutes · four options each
Selective test
40 questions · 40 minutes · four options each
What it tests
Reasoning, not curriculum content

What it actually tests

The questions fall into a few recognisable families:

  • Logical deduction — working out what must be true from a set of clues or conditions.
  • Sequences and patterns — spotting the rule behind a series of numbers, shapes or symbols and continuing it.
  • Spatial and abstract reasoning — manipulating shapes, nets and figures in the mind’s eye.
  • Evaluating arguments — judging whether a conclusion follows, and identifying flaws or unstated assumptions.

None of these depend on remembering facts. They depend on reading carefully, reasoning precisely and not jumping to the obvious-looking answer.

Why strong school students underperform

This is the bit worth understanding. School rewards children who absorb and recall content well — and Thinking Skills offers nothing to recall. There’s no chapter to revise, no formula to memorise. A child who is used to being right because they know the material can feel unsettled when the answer has to be worked out from scratch under time pressure.

How to build it gradually

Because it’s a way of thinking rather than a body of knowledge, Thinking Skills responds well to steady, low-pressure exposure.

  • Start untimed. Let your child understand each question type properly before adding the clock.
  • Talk through the reasoning. Ask “how did you eliminate the other options?” — the method is the skill.
  • Add timing later. Once the types are familiar, gentle timed practice builds the pace the real test demands, especially the brisk OC section.
  • Spread it out. A little, often, beats an intense burst — reasoning matures with practice over months.

Where Test Academy fits

Thinking Skills rewards volume and variety of well-explained practice, which is hard to assemble at home. Test Academy’s platform provides a deep, adaptive bank of Thinking Skills questions with worked explanations, so a child sees plenty of types and learns why each answer is right — which is exactly how this section is built. It pairs naturally with the related Mathematical Reasoning section, which shares the same problem-solving mindset.

Frequently asked questions

What is the Thinking Skills section?

It tests reasoning rather than curriculum knowledge — logical deduction, sequences and patterns, spatial and abstract reasoning, and judging the strength of arguments. It appears in both the OC and Selective tests with four options per question.

Why do strong students struggle with Thinking Skills?

Because it isn't taught at school. A child can be top of the class and still find these questions unfamiliar, since there's no body of content to revise — only a way of thinking that needs practice.
