Computing and AI (Full version) in 8 minutes.

It suits curious learners and anyone revising computing and AI fundamentals. It checks practical knowledge of Excel formulas, system architecture and AI ethics, helping you identify weak areas before an exam or simply to satisfy your curiosity about your current level.

The Short version has 10 questions and about 3 minutes, ideal for a quick snapshot at any level. The Full version has 30 questions and gives a more precise score, taking longer depending on the level you select.

Revise spreadsheet formula logic, operating system shortcuts and network protocols without memorising exact answers. During the test, use the Hint for a method tip with no score penalty, and select Bookmark for review to flag questions you want to return to.

You pass with 6 correct out of 10 on Short versions, or 18 out of 30 on Full versions. The result band is Needs work below 40%, Intermediate from 40%, Advanced from 60%, and Expert from 80% only at Expert level.

Yes, choose Start again as often as you want. Questions stay the same in the same order, so retakes mostly measure memory. Only your best attempt counts for rankings: highest score, then shortest time as the tie-break.

The rankings show only your first name and last initial, country, city, score and time. Nobody else can see your result: it is visible only to you. You can request deletion of your personal data from the site's data rights page.

Passing earns a PDF certificate with first and last name, score, date, a certificate number and a QR code that opens a verification page. It is attached to the result email and downloadable from your account.
