Adaptive questions
Each answer sets the next question. Right answers lead to harder ones, wrong answers to easier ones, so the test finds your level quickly.

One clock, like Raven's
33 minutes for the whole test, the same pace as Raven's Advanced Progressive Matrices. Unanswered questions count as wrong when time is up.
Scored the way modern tests are

What it measures
Fluid intelligence: reasoning and problem solving with new information. It is the core of what IQ tests measure. A full clinical assessment (such as the WAIS, given by a psychologist) also covers vocabulary, memory and processing speed. This test is not a diagnosis.

Questions
Is this a real IQ test?
It measures fluid reasoning, the core of IQ, with the methods modern tests use: adaptive questions and item response theory scoring on the standard scale (average 100, standard deviation 15). The norms are refined from the results of everyone who takes it. It is not a clinical diagnosis.
How long does it take?
33 minutes for 30 questions, plus three untimed practice questions first.
Can I take it in Arabic?
Yes. Switch to Arabic at the top of the page. The questions are mostly shapes and numbers, so the language does not change the difficulty.
Is it free?
Yes. The test and your IQ score are free. The full report, certificate and IQ Pro are optional.
Why only one free attempt a month?
Taking the same kind of test again soon raises scores through practice, not ability. Real IQ tests limit retakes for the same reason. IQ Pro removes the wait for people who want to practise.
How is cheating handled?
Questions are generated fresh for every test, so there is no answer list to find. The server keeps the clock. Leaving the page is recorded, and a test where the person left the page more than twice does not count for the leaderboard.
Can I put the certificate on my CV?
Yes. Each certificate has a unique number, a QR code and a public verification page, so an employer can confirm it is genuine. It certifies your result on the Cardify adaptive IQ test; it is not a clinical diagnosis.
