Numerical Concentration Tests (NCT) are used by many employers to measure a candidate s attention to detail. In particular, they are used by some train operating companies, to establish the potential of applicants. These tests will examine your ability to concentrate and produce effective results, whilst under timed pressure.
Even if your assessment does not include a version of a numerical concentration test, by practising these tests you can improve your concentration levels, your attention to detail and your ability to work under timed pressure.
In each question, you will be given four pairs of digits. These can either consist entirely of numbers, or will be a combination of both letters and numbers. Three of the pairs will have matching digits. In order to solve the question, you will have to make a visual comparison to identify which pair of numbers/letters does not match.
