What is genius IQ scores range?

You can find in the Stanford – Binet Intelligence Scale 5th edition that an average IQ score will be around 80 and 119. Scores which are closer to 80 are Low average and those which closer to 119 are High average. The next level considered as Superior is between 120 and 129 and Gifted is from 130 and 145. But “smart” and “intelligent” are not totally the same. Intelligence is the way to measure someone’s ability to adapt themselves to new situations, and even find the best solution for that at the moment. For this concept, you can imagine that being intelligent and being smart are as closely linked as being a good driver and a good mechanic, just because you know how to drive a car doesn’t mean you know about what makes it work.
