Civil Service Numerical Test study plan

Civil Service Numerical Test · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Basic number operations and arithmetic fluency

Drill multiplication tables to 15×15 and squares to 30² until each fact is recalled in under two seconds
Complete eight timed 20-question arithmetic sprints covering whole numbers, decimals and signed numbers
Memorise fraction–decimal–percentage equivalents for the twenty most common fractions and test them cold daily
Record every missed item in an error journal with the correct method written out in full

A 40-question timed arithmetic test (20 minutes) scored at 90% or above, backed by error-journal entries for every miss

Week 2

Interpret twelve multi-column tables, computing totals, differences and percentage shares under a 90-second-per-question cap
Apply order of operations and negative-number rules across five mixed sets of 25 items
Restate the exact quantity each question requests before calculating, on twenty table questions
Re-solve every item missed in week 1 and confirm each is now correct without notes

Twelve completed table-interpretation sets at 85% accuracy or better plus a one-page checklist of recurring misreads

Week 3

Work through bar, line, pie and stacked charts, computing percentage change and share of total across at least thirty questions
Read axis scales, units and legends precisely on fifteen questions built with misleading scales
Time-box each data-interpretation question to 75 seconds and log every overrun
Distil chart question types into a one-page method sheet listing the calculation each type demands

One full timed data-interpretation section of 25 questions in 30 minutes at 80% accuracy or better, with a per-question timing log

Week 4

Convert among fractions, decimals and percentages across 100 rapid items
Solve thirty percentage problems spanning percentage change, reverse percentage and successive percentage change
Solve twenty-five ratio and proportion problems including part-to-whole, sharing and scaling
Re-test data interpretation under strict timing now that percentage methods are faster

A 30-question mixed set combining percentages, ratios and data interpretation, scored at 80% or better under exam timing

Week 5

Compute simple, weighted and combined-group averages across twenty-five problems
Solve twenty-five rate problems covering speed, work rates and flow rates
Convert units of length, mass, volume, time and currency across forty items without a calculator
Chain proportional reasoning through multi-step unit conversions and check each result for scale plausibility

A 25-question averages, rates and conversions quiz at 85% or better with fully worked solutions for every error

Week 6

Translate twenty word problems into equations before attempting any arithmetic
Solve multi-step applied problems involving discounts, tax, profit and loss
Compute budget variances, percentage of budget spent and simple interest across twenty items
Estimate each answer to one significant figure first, then compare it against the exact result

A 20-question financial and word-problem set at 80% or better with an estimation cross-check written beside every answer

Week 7

Practise rounding and front-end estimation on fifty items, selecting answer ranges rather than exact values
Answer thirty questions in twenty minutes using estimation shortcuts wherever the options permit it
Re-drill the arithmetic facts flagged as slowest in the error journal
Condense all domain notes into a two-page revision sheet

A 30-question speed set finished in 20 minutes at 80% accuracy or better, using at least ten documented estimation shortcuts

Week 8

Sit three full timed mocks under strict exam conditions with no pauses
Analyse every mock error within 24 hours and re-solve each missed question unaided
Rehearse a per-question time budget and a skip-and-return strategy for hard data-interpretation items
Give the two-page revision sheet a final pass and correct any gaps found in mocks

Three full mock scores trending upward, with the final mock at 85% or above and an accompanying error-analysis sheet

Week 4: Full-length diagnostic mock scored at 70% or above overall, with domain 1 accuracy at 85% or above and domain 2 at 75% or above

Week 6: Second full mock at 78% or above overall, with domains 5 and 6 each at 75% or above and no unanswered questions

Week 8: Three completed timed mocks with the final score at 85% or above and every logged error re-solved and verified
