120 is high IQ score.
It is higher than 85 percent of all results.
It is higher than 94.4 percent of all results.

It means you have above average reasoning and problem-solving skills. Studies suggest that people with higher IQ tend to have more chances to be better in school, job performance and be healthier in general. But not always.

"A high IQ is like height in a basketball player," says David Perkins, who studies thinking and reasoning skills at Harvard Graduate School of Education in Cambridge, Massachusetts. "It is very important, all other things being equal. But all other things aren't equal. There's a lot more to being a good basketball player than being tall, and there's a lot more to being a good thinker than having a high IQ."

There are many ways that can help a person increase their IQ as well as improve their brain function like constantly learning something new, frequent reading, learning new languages, physical exercise, proper nutrition and other activities.
