18 of 51 cards from the Aptitude, Reasoning and Psychometric Testing deck — real questions with worked answers.

1. What is the primary purpose of the aptitude tests at the AOSB?

   To provide an objective, standardised measure of a candidate's reasoning ability (verbal, numerical and abstract) that screens potential to cope with the intellectual demands of officer training, independent of background or schooling.

2. At which stage of the AOSB process are aptitude tests sat, and what is their gatekeeping role?

   They are sat early (at the AOSB Briefing/Main Board), and a minimum aptitude threshold acts as a gate: scores below the cut-off can bar progression regardless of strong performance elsewhere.

3. How do aptitude scores typically combine with other AOSB assessments in the final decision?

   Aptitude is one weighted strand alongside physical, leadership (command tasks), planning exercise and interview performance; it informs but does not solely determine the overall pass, and a borderline score can be offset by strong all-round performance.

4. Name the three broad ability domains AOSB aptitude testing assesses.

   Verbal reasoning, numerical reasoning, and abstract/non-verbal (spatial and logical) reasoning.

5. Why are AOSB aptitude tests strictly timed?

   Timing standardises conditions for all candidates and measures reasoning under pressure, which mirrors the rapid, accurate decision-making required of an officer.

6. How is the typical AOSB aptitude test scored, and is there a penalty for wrong answers?

   Scoring is usually number-correct (raw marks converted to a standardised score); there is normally no negative marking, so every question should be attempted even if guessed.

7. Given no negative marking, what is the optimal answering strategy when time runs out on an aptitude test?

   Make an educated or even blind guess on every remaining question, because a guess has positive expected value and a blank scores zero.

8. Define the speed-accuracy trade-off in the context of timed aptitude tests.

   It is the inverse relationship whereby working faster tends to reduce accuracy and working more carefully reduces the number of items attempted; the goal is the pace that maximises total correct answers.

9. What pacing rule helps avoid losing marks on hard early questions in an aptitude test?

   Allocate roughly equal time per question, and if a question exceeds its time budget, mark a best guess and move on rather than letting one item consume time meant for several others.

10. If a numerical test has 30 questions in 15 minutes, what is the average time budget per question?

    $\frac{15 \text{ min}}{30} = 30$ seconds per question.

11. What is the difference between comprehension and inference when reading a passage?

    Comprehension is identifying what the passage explicitly states; inference is drawing a logically supported conclusion that is implied but not directly stated.

12. In verbal reasoning, how should a 'True / False / Cannot Say' item be judged?

    Use only information given in the passage: True if the statement must follow, False if it contradicts the passage, and Cannot Say if the passage gives insufficient information to decide either way.

13. What is a common trap in inference questions involving outside knowledge?

    Selecting an answer that is true in the real world but not supported by the passage; valid inference must rest solely on the text provided.

14. Define logical deduction.

    Reasoning from given premises to a conclusion that must be true if the premises are true; the conclusion is fully contained within the premises.

15. In an argument, what is an assumption?

    An unstated premise that must be true for the argument's conclusion to logically follow from its stated premises.

16. How can you test whether a statement is a necessary assumption of an argument?

    Apply the negation test: if negating the statement makes the argument fall apart, it is a necessary assumption; if the argument still holds, it is not.

17. Distinguish a valid argument from a sound argument.

    A valid argument has a conclusion that follows logically from its premises; a sound argument is valid AND has all true premises.

18. In a verbal analogy 'A is to B as C is to D', what is the first step to solving it?

    Identify the precise relationship between A and B (e.g. cause-effect, part-whole, opposite, degree), then apply that exact relationship to C to find D.
