IQ Test in 5 minutes.

It measures reasoning across logic, sequence patterns, geometry and numerical problems. It suits learners or curious readers who want to practise cognitive ability, and people preparing for exams that involve similar mental challenges.

There are Easy, Intermediate and Expert levels, each in a Short version of 10 questions for about 5 minutes or a Full version of 30 questions for 13 to 15 minutes. Choose Short for a quick overview; Full gives a more precise score.

Practise recognising number and shape sequences, mental rotation, mirror reflection and formal logic statements. Work through problems untimed first, then repeat under the same countdown pressure. Revise percentage changes, set logic and counting methods.

Your result shows the number of correct answers. Bands are Needs work below 40%, Intermediate from 40%, Advanced from 60% and Expert from 80% only at Expert level; other levels top out at Advanced. A pass earns a PDF certificate with score, date, certificate number and QR code.

Yes. Use 'Start again' as often as you want. The questions are the same and in the same order, so a retake mostly measures memory rather than fresh reasoning.

Rankings can be filtered by test, country and city. They show only first name, last-name initial, country, city, score and time. Only your best attempt counts: highest score, then shortest time.

A result is visible only to the person who took the test. You can request deletion of your personal data from the site's data rights page; it is a request, not an instant button.
