People with an IQ of 200, 90 ~ 1 10 belong to the normal intelligence range, those with an IQ of 120 ~ 140 are smart people, and those with an IQ of 140 or above are called geniuses. The lower the score, the worse the intelligence. Anyone below 70 points is mentally retarded. Among them, 50-70 points are idiots, 25-50 points are dementia, and 0-25 points are idiots.

Four ways to improve IQ:

First, change children's eating habits; Second, create an inspiring and emotional environment for children; Third, improve children's emotional IQ; Fourth, guide children to set goals and inspire them to think creatively.

PS: 12 years old, it is very good to have such an IQ!
