24 sample cards from the Test Strategy, Timing and Accuracy deck

Sampled from the end of the deck, so these are different cards from the ones shown on the syllabus page.

  1. State the formula to find a part as a percentage of a whole.

    $$\text{percentage} = \frac{\text{part}}{\text{whole}} \times 100\%$$

  2. How do you increase a value $V$ by $p\%$ in one step?

    $$V_{\text{new}} = V \times \left(1 + \frac{p}{100}\right)$$

  3. How do you decrease a value $V$ by $p\%$ in one step?

    $$V_{\text{new}} = V \times \left(1 - \frac{p}{100}\right)$$

  4. What unit-related mistake is especially common when charts use axis labels like 'figures in £000s'?

    Forgetting to multiply by 1000, so a bar reading '45' is treated as £45 instead of £45,000.

  5. State the formula for converting a ratio to a fraction of the total for the ratio $a:b$.

    The first part is $\frac{a}{a+b}$ and the second is $\frac{b}{a+b}$ of the total.

  6. How do you split a total amount $T$ in the ratio $a:b:c$?

    Each share is $\frac{a}{a+b+c}T$, $\frac{b}{a+b+c}T$ and $\frac{c}{a+b+c}T$ respectively.

  7. What is the formula for an average (arithmetic mean) of $n$ values?

    $$\bar{x} = \frac{\sum_{i=1}^{n} x_{i}}{n}$$

  8. How do you reverse a percentage increase to find the original value, given a value $F$ after a $p\%$ rise?

    $$\text{original} = \frac{F}{1 + \frac{p}{100}}$$ — divide by the multiplier, do not subtract $p\%$ of $F$.

  9. Why is subtracting $p\%$ of the final value a classic error when reversing a percentage increase?

    Because the percentage was applied to the smaller original value, not the larger final value, so subtracting overstates the original.

  10. What are the key elements of an effective numerical-test practice routine?

    Regular timed practice, reviewing every wrong answer to find the error type, drilling weak operations, and gradually increasing speed under time pressure.

  11. Why should practice for the online test be done under timed conditions rather than untimed?

    Because the real test's main difficulty is time pressure; untimed practice builds accuracy but not the pacing and decision-making needed on the day.

  12. In a practice routine, what should you do with every question you got wrong?

    Diagnose the cause (misread, wrong operation, calculation slip, unit error) and categorise it so you can target the recurring weakness.

  13. What is 'deliberate practice' applied to numerical reasoning?

    Focused, repeated drilling of your specific weak areas (e.g. percentage change, ratios) with immediate feedback, rather than just doing random mixed tests.

  14. How does spaced repetition support numerical-test preparation?

    Revisiting formulas and question types at increasing intervals strengthens long-term recall, so methods are automatic and fast under exam pressure.

  15. What is the benefit of mastering mental-arithmetic shortcuts as part of a practice routine?

    They cut reliance on the calculator for simple steps, saving seconds per question that accumulate into a meaningful time advantage.

  16. What are 'reasonable adjustments' in the context of the Civil Service online numerical test?

    Changes to test conditions (such as extra time, screen-reader compatibility, or coloured overlays) made to remove disadvantage for candidates with a disability or specific need.

  17. Give two examples of common reasonable adjustments for a numerical reasoning test.

    Additional time allowance (e.g. 25% or 50% extra) and assistive technology such as screen readers, magnification, or modified colour contrast.

  18. When should a candidate request reasonable adjustments for the test?

    As early as possible during the application stage, before sitting the test, so arrangements can be confirmed and put in place in time.

  19. What legal principle underpins reasonable adjustments in UK Civil Service recruitment tests?

    The duty under the Equality Act 2010 to make reasonable adjustments so disabled candidates are not placed at a substantial disadvantage.

  20. How does extra time as a reasonable adjustment change your pacing calculation?

    It increases $T_{\text{total}}$, so $t_{\text{per question}} = \frac{T_{\text{total}}}{N}$ rises; e.g. 25% extra time multiplies the per-question budget by 1.25.

  21. List three practical techniques for managing test-day nerves before a numerical test.

    Controlled slow breathing, positive reframing of anxiety as readiness, and arriving prepared with formulas rehearsed to build confidence.

  22. Why can starting with the easiest questions help manage test-day anxiety?

    Early correct answers build momentum and confidence, lowering stress so the harder questions feel more manageable.

  23. How does familiarity with the test format reduce test-day nerves?

    Practising the exact question types, calculator and tools removes surprises, so cognitive effort goes to solving rather than navigating the interface.

  24. What breathing-based technique is commonly recommended to steady nerves before answering?

    Slow diaphragmatic breathing (e.g. inhale for 4 counts, exhale for 6) to lower heart rate and refocus attention before reading the question.

What this deck covers

The Test Strategy, Timing and Accuracy deck follows the Civil Service Numerical Reasoning Test Test Strategy, Timing and Accuracy syllabus — 3 chapters and 9 topics — so questions land on material that is genuinely examinable rather than trivia around it. That works out to roughly 16.7 cards per chapter.

Answers are written to be recallable, not just readable — averaging about 121 characters, which is long enough to carry the reasoning and short enough to say out loud.

A deck like this earns its keep on the second and third pass. Read the syllabus first so you know the shape of the subject, then use the cards to find the specific facts that have not stuck.
