IQ (intelligence quotient) is a measurement of an individual’s cognitive ability. It indicates where an individual ranks in a large population. Normally, IQ tests assess logical reasoning, language skills, problem-solving skills, mathematical aptitude, and spatial recognition.

What Is An IQ Test?

An IQ test, or Intelligence Quotient test, is a standardized assessment designed to measure human intelligence. It evaluates a range of cognitive abilities, including logical reasoning, problem-solving, numerical aptitude, verbal comprehension, and spatial awareness. The results of an IQ test are expressed as a single numerical score, which reflects an individual's cognitive abilities relative to the general population.

Basically, the test is designed to adapt to the individual’s demand of unveiling their IQ potential as well as an IQ self-understanding journey.
