Selective Thinking Skills — Question Types & How to Practise (2026)

1. What Thinking Skills really tests

Selective Thinking Skills tests how students reason when the answer is not obvious. It assesses the ability to analyse information, identify patterns, evaluate arguments and solve unfamiliar problems under time pressure.

Core skills being assessed

• Logical reasoning: using rules or conditions to work out what must be true
• Critical thinking: judging whether an argument is strong, weak, supported or unsupported
• Pattern recognition: identifying relationships between shapes, numbers, words or ideas
• Problem solving: deciding which information matters and testing possibilities efficiently
• Careful reading: noticing small wording changes that affect the answer

2. Core question patterns

Thinking Skills can feel unpredictable because the surface of the question changes. The underlying reasoning patterns, however, can be practised.

Deductive reasoning

• Ordering and arrangement puzzles
• Conditional statements: if this, then that
• Must be true / cannot be true questions
• Matching people, objects or categories using constraints
• Eliminating impossible options

Evaluative reasoning

• Identifying assumptions
• Choosing the strongest evidence
• Finding flaws in an argument
• Strengthening or weakening a claim
• Distinguishing fact, opinion and conclusion

Problem solving and patterns

• Sequences and rule-based patterns
• Data interpretation with hidden constraints
• Spatial or visual reasoning tasks
• Questions where answer choices must be tested systematically

3. Timing & pacing cues

Students have 40 minutes for 40 questions, so the average is exactly one minute per question. This makes pacing especially important.

A practical pacing approach

• Move quickly through familiar patterns: do not over-explain easy questions during the test
• Flag sticky questions: if a puzzle is not opening up after 60–90 seconds, move on
• Use elimination: removing impossible options is often faster than proving the correct option from scratch
• Protect the end of the section: students should avoid leaving several unanswered questions because one earlier item absorbed too much time

Working paper strategy

• Use small diagrams or tables for arrangement puzzles
• Write abbreviations instead of full names
• Cross out impossible pairings
• Keep working neat enough to return to a flagged question later

4. Mistakes to avoid

• Guessing from intuition too quickly: Thinking Skills rewards structured reasoning, not vibes.
• Trying to hold all conditions in memory: students should use working paper for logic puzzles.
• Missing absolute wording: “must”, “could”, “cannot”, “all”, “some” and “only” are crucial.
• Spending too long proving every option: elimination is often enough.
• Reviewing only the final answer: students need to understand the reasoning pattern they missed.

5. Practise the right way

Thinking Skills improves through deliberate pattern exposure. The goal is to help students recognise the type of reasoning required and choose an efficient method.

Use targeted reasoning practice

• Group practice by reasoning type: deduction, argument, patterns, data or visual-spatial reasoning
• Practise one method at a time before mixing question types
• Ask students to explain why wrong answers fail
• Track repeated mistakes so future practice is more focused

Use timed mixed practice

Once students know the methods, mixed timed sets help them switch between reasoning types quickly. This is closer to the actual test experience.

Review the method, not just the score

A low score in Thinking Skills is often frustrating because the content does not look like normal schoolwork. Review should focus on the thinking move: drawing a table, testing cases, identifying an assumption or eliminating a contradiction.

• How many questions are in Selective Thinking Skills?

  Students have 40 minutes to answer 40 multiple-choice questions.
• Does Thinking Skills require prior knowledge?

  No specific subject knowledge is required. The section assesses critical thinking and problem solving, but students still benefit from learning common reasoning strategies.
• How can my child improve at logic puzzles?

  Use working paper. Tables, diagrams and systematic elimination make logic puzzles much easier than trying to hold everything in memory.
• Why does my child do well untimed but poorly under test conditions?

  Thinking Skills timing is tight. Students need to recognise question patterns quickly, avoid getting stuck, and practise moving on from low-return questions.
• What is the best way to review Thinking Skills mistakes?

  Classify the reasoning error: missed condition, weak elimination, wrong assumption, careless wording or poor diagram. Then redo a similar question using the correct method.
