IQ is a 200-point scale. Those with a score of 90 to 110 are within the normal intelligence range, those with a score of 120 to 140 are considered smart, and those with a score of 140 or above are called geniuses. The lower the score, the worse the intelligence. Those with scores below 70 are intelligent. IQ is a quantitative indicator that indicates the level of a person's intelligence. It was proposed by German psychologist Stern in 1912
