Maths (Full version) in 15 minutes.

It measures logic and numerical accuracy across geometry, percentage changes and functional analysis. It suits learners, curious readers or anyone revising for a maths exam.

Choose “Easy”, “Intermediate” or “Expert” from the level selector, then “Short version” for a quick overview or “Full version” for a more precise score. Short lasts about 5 minutes; Full lasts about 13 to 15 minutes.

Revise linear equations, fractions, probabilities, Euclidean geometry, perimeters, percentages and graph reading. Practise multi-step equations and reverse percentage calculations. Use each question’s “Hint” for a method tip that never lowers your score.

Each correct answer scores one point. The result shows a band from the share of correct answers: below 40% “Needs work”, from 40% “Intermediate”, from 60% “Advanced”, from 80% “Expert” only at the Expert level.

You pass with at least 6 correct out of 10 on a short version or 18 out of 30 on a full version. A pass earns a PDF certificate with first and last name, score, date, certificate number and a QR code, attached to the result email.

Use “Start again” whenever you like; questions stay the same, so retakes mostly measure memory. Rankings show only your best attempt: highest score, then shortest time, with first name, last initial, country, city, score and time.

Your result is visible only to you. Rankings, if unlocked, show only first name, last initial, country, city, score and time. You can request deletion from the site’s data rights page.
