Online IQ test
To take the IQ test, study the pattern shown at the top of each question and select the alternative that completes the sequence in the most logical way.
What does this IQ test evaluate?
This test follows the principle of progressive matrices (Raven): it measures abstract reasoning — the basis of logical problem-solving — using information perceived by the senses.
Who can take the test?
Recommended for people aged 12 to 65, from any culture, language, or education level. It does not require advanced vocabulary and focuses on visual patterns and logic.
How does the test work?
The test is divided into short blocks totaling 35 questions. Difficulty gradually increases, requiring attention to rules and transformations in the patterns.
What can influence the result?
IQ is multifactorial. The score should not be used as the only measure of intelligence or thinking.
