Original practice bank · All explanations and revision guides free
Solve 30 original arithmetic, percentage, ratio, data and rate tasks. All worked answers and five full guides free. Untimed, no signup or hiring score.
30 questions · about 18 minutes · no signup
Answer 30 original four-option questions, six in each section. Each has one checked answer under its stated quantities, units and assumptions. A correct choice adds one; another valid choice zero. There is no timer, guessing penalty, partial credit or speed adjustment. You may use paper or a calculator. Round only when a question explicitly asks, at the final step. Finish all items for every worked answer and all five full guides. Eighteen minutes is an editorial estimate, not observed completion data.
Preparing the test…
All questions and full results are free, with no signup. Saving is optional; only saved attempts can be resumed after a refresh or language change. Tab drafts expire after 24 hours and clear on completion or retake.
Read fictional quantities, choose the operation and keep its units. This full original practice covers arithmetic setup, percentage bases, ratios, small data tables described in words, and rates or conversions. Separate exact-fraction calculations check all 30 keys and the stated final rounding; fresh guide examples are also checked. This is answer-bank verification, not psychometric validation. All 120 alternatives, 30 rationales and five complete revision guides are free. No SHL, Kenexa, Cubiks, GMAT or JobCannon question bank, licensed score or norm is used. Counts do not measure speed, intelligence, job readiness, professional competence or future test performance. No percentile, employer pass threshold, cross-language calibration or fairness study is established. Number-series puzzles are a separate topic rather than part of this edition.
Every section has a public revision guide. Completing the practice shows every guide and item explanation without assigning a type by score. Public guides contain no personal responses or counts; studying before practice is welcome. This is not a secure exam.
Review totals, balances, equal-group averages and unit-aware arithmetic with fresh examples. Six answers describe practice, without a speed or ability band.
Work through shares, original-value changes, reverse percentages and successive changes. Fresh examples separate percentages from percentage points.
Review ratio parts, chained comparisons, scaling and unequal denominators with fresh calculations. Six-item counts are local practice, not a certified score.
Practise row selection, scaled units, weighted means and pooled percentages. Fresh tables show why counts and rates can rank groups differently.
Review average output, decimal time, concurrent rates and fictional unit conversions. Fresh examples preserve assumptions and distinguish time from rate.
Yes. All 30 items, selected choices, checked keys, worked explanations and five complete guides are free, with no account, email, payment or certificate purchase. Public revision guides can be read before an attempt.
No. It is an independent untimed practice bank, not SHL, Kenexa, Cubiks, GMAT or another employer’s instrument. It supplies no norm, percentile, hiring threshold, professional qualification or prediction of another test score.
Yes. The count checks your selected answers, without distinguishing mental calculation from assisted working. If you compare your own attempts, record what help you used. There is no speed score; eighteen minutes is an editorial estimate.
No. Counts describe these fictional quantities and stated assumptions only. Inspect whether the error concerns the chosen quantity, denominator, unit, weighted total or operation. No calibrated ability category, clinical interpretation or fixed personal trait is inferred.
Yes. You can go back and optionally save a browser-tab draft for up to 24 hours; completion, retake or exit-and-clear removes it. Without a saved draft, refresh loses progress. Repeating familiar keys can reflect recall, not a change in general ability.
Only the public test title and link, without choices, correctness counts, keys, draft data or private identifiers. Your answers do not enter the shared URL, and the tool does not create an inferred ability label for sharing.
Five groups of six questions produce a total correct count out of 30. Every matched key adds one, without weighting, reverse scoring or timing. All choices must be valid before the report appears; missing answers are not silently treated as wrong. Every key, rationale and complete guide appears at zero, partial and perfect counts. The five public guides are revision topics, not ranked outcome types.
For a fresh example, 15 boxes with 14 pieces each contain 210 pieces. If 38 are used, 172 remain. A question asking for the starting count needs 210; one asking for the remainder needs 172. In percentage and rate items, the denominator is equally important. Every scenario explicitly states ideal assumptions such as constant output, disjoint groups or additive volumes; do not extend those assumptions to real operations without evidence.
Only the comparison of 40/60 and 54/90 requests a final one-decimal rounding: their share difference is exactly 1/15, or 6.666… percentage points, giving 6.7. Other keys use the exact quantities specified. Percentage points and relative percent change are distinct units. For a share moving from 15% to 21%, the change is six percentage points, while the relative increase is 40%.
FermatMind independently wrote every task, option, rationale and guide. Exact arithmetic verifies supplied fictional quantities, unique numeric options and stated rounding, without borrowing vendor items or OpenStax examples. References explain mathematics or their own product context; they do not endorse this bank or establish score equivalence. No clinical, hiring, salary, training-gain or real financial-advice conclusion follows from the count.
