What we do?

How Does The IQ Test Work?

The IQ test encompasses a series of tasks designed to evaluate different aspects of intelligence, such as short-term memory, analytical thinking, mathematical prowess, and spatial recognition. It's important to note that this test doesn't quantify the amount of knowledge you've accumulated, but rather, it assesses your potential to learn. After you provide your responses, we compare your performance with people in your age group, and then offer a normalized score. Interpreting a normalized score might be challenging for those without familiarity in statistics. Therefore, it's more beneficial to perceive your score as a numerical representation of your IQ in relation to others, rather than a definitive assessment of intelligence.

The IQ score is derived from a series of tasks evaluating various cognitive abilities, such as memory, reasoning, problem-solving, and comprehension. This score reflects your potential to learn and understand new information. It’s important to remember that an IQ test measures potential rather than acquired knowledge. After completing the test, your performance is compared to others in your age group, providing a normalized score that indicates where you stand relative to your peers.
