It's interesting to note that nowadays intelligence can be measured. During the olden days people didn't give so much attention as to their nuts, with the exception of those who were fully aware of their state. Then in 1905, a French psychologist named Alfred Binet became worried about those concerned - he can qualify as a philanthropist - he devised the earliest intelligence tests. From then on the tests were of good use to all humanity, but was brought forth to be subjected to investigation. Nevertheless, the popularity of Binet's innovation prompted William Stern, a German psychologist, to coin the term Intelligence Quotient, which is fairly used and abused from the time being.

From 80 to 90 IQ … low normal individuals
From 90 to 110 IQ … normal average individuals
From 110 to 120 IQ … high average individuals
From 120 to 140 IQ … superior individuals
From 140 IQ onwards … very superior individuals; aliens
Just a piece of advice. Though IQ tests may sound so awe-inspiring, remarkable, and truthful, don’t be easily fooled by these things. Like horoscopes, they all wallow in the concept of Barnum effect, i.e. generalized descriptions and/or statements which are ambiguous in nature, and we tend to believe in them due to fallacies of positive instances. Also, it may be construed that these are somehow subjective in its sense, and some of the psychologist’s biases tend to be incorporated in conclusions regarding these tests. So before taking those tests, just take in to consideration these concepts.
By the way, there’s this online personality assessment test by Dr. John A. Johnson. Take time in answering any of the two. Here's the link for the shorter version.
