An IQ test measures your cognitive abilities, such as logical reasoning, pattern recognition, problem-solving skills, and short-term memory. The results are then expressed as a score called the intelligence quotient (IQ), which typically ranges from 40 to 160.
Generally speaking, IQ tests consist of multiple-choice questions that ask you to pick the next element in a sequence based on the previous ones. To solve these tasks, you must employ your analytical and deductive skills and work out the pattern that governs the sequence.
According to Wechsler’s widely accepted IQ test scale, an IQ score is calculated by comparing your results to those of your peers in the same age group. For example, if you do the test better than 86% of your generation, your result will be between 115 and 120. On the other hand, the worse you do compared to others, the lower your score.
The average IQ score is between 85 and 115, with over two-thirds of the population falling within this IQ test range. Any score under 85 is considered low, while those who score above 115 are appraised as gifted. The further you go toward either extreme, the fewer people share your IQ.
