Korn Ferry numerical test guide

Read tables, choose the right figures and calculate under an individual question clock.

Choose a practice drill

Know the format

Questions12
Time90 seconds for the first question on a dataset, then 75 seconds for each follow-up.
Answer controlsChoose one value from a dropdown. Check units and the requested rounding before submitting.
What to have readyHave a calculator, paper and pen ready. Korn Ferry recommends these for Elements Numerical.

There is a fresh time allowance for each question. Submit when ready; time saved on one question does not carry forward. If the timer expires, the selected answer is submitted automatically. You cannot return to earlier questions.

Practice each skill

Percentages and change

Write down the base quantity first. For a change, divide by the original value. To combine percentages, calculate the underlying counts before adding.

Common mistake: Percentage points and percentage change are different. An unweighted average can be wrong when the group sizes differ.

Practice percentages and change

Ratios and rates

Convert quantities to a common unit, keep the numerator and denominator labeled, and estimate the scale of the answer before using your calculator.

Common mistake: A rate per person is not a total. A monthly figure cannot be compared directly with an annual figure.

Practice ratios and rates

Multi-step calculations

Work backward from the requested output. Keep intermediate values unrounded, apply conditions in order, and round only as the question instructs.

Common mistake: Revenue, profit and margin have different denominators. Close answer options often reflect a skipped step rather than a rounding error.

Practice multi-step calculations

Move from learning to timing

  1. Start with an untimed drill. Explain why your chosen answer follows and why the alternatives fail.
  2. Read the worked solutions, then practice the skill that caused the error. Check recorded exposure when repeating familiar questions.
  3. Take a full test under the individual question clocks. Use the same equipment and a quiet setting you expect for your real test.
  4. Review accuracy alongside unanswered questions, timeouts and Challenge performance. Aim for the practice goals consistently across different question sets.

Understand your practice results

The real Elements assessment adapts its questions to your performance. Our full practice uses a fixed mix weighted toward Challenge questions, so you can rehearse demanding tasks and the published timing. A raw practice score is not Korn Ferry’s normed percentile. Employers choose their own benchmarks; there is no universal pass mark.

Drill explanations wait until the whole passage or dataset is complete; logical explanations follow each question. Full-test feedback waits until the end. Progress charts appear after a second comparable attempt, while saved reviews remain available from the first.
