Borderline?
Well technically, if anybody did a research on what their TRUE IQ is, they should know what it means.
It's a measure of your intelligence, compared to your biological age. The formula is:
IQ = Mental age / chronological age (real age) x 100
So technically, an average person has an IQ of 100, as their mental age is identical to their chronological age. If the person is "smart", their IQ will be above 100, while a "stupid" person will have an IQ below 100.
So to answer xXmuffin0manXx, there is no borderline; anybody with an IQ of less than 100 is less intelligent.
That was basically what was proposed, but IQ is now calculated a different way now. But still, it holds true for 100 IQ to be average, >100 IQ to be "more intelligent", and <100 IQ to be "less intelligent"
