What we do?

How Does The IQ Test Work?

The IQ test consists of a number of tasks measuring various measures of intelligence including short-term memory, analytical thinking, mathematical ability and spatial recognition. Like all IQ tests it does not attempt to measure the amount of information you have learned but rather your capacity to learn. Once you've provided your answers we compare your results to people of your age and then we provide a normalized score. Normalized scoring can be difficult to understand for those without a background in statistics. It's best to think of your score as a number which represents your IQ compared to others, not as a measure of intelligence.
