Put your mind to the test!

The history of IQ testing started about 100 years ago, up to that point the terms like "IQ“ or "IQ test“ were not widely used. The work intelligence comes from Latin and initially, it did not have the meaning relating to an individual's ability to solve tasks, it related to the brain and its ability to deal with mental questions.

This IQ test is thus able to differentiate between individuals according to their capacity for immediate observation and their logical reasoning and determine their learning potential.
