The average IQ is 100. (Then again -- think about how dumb the 'average person' is. ;-)
Quick google turned up the following: "Joseph Matarazzo's leading text on intelligence and the National Longitudinal Survey of Youth: The average IQ is about 105 for high school graduates, 115 for college graduates and 125 for people with advanced professional degrees."
So if that is true, then an IQ of 120 would put you slightly above the median for college material.
Also: See http://www.assessmentpsychology.com/iqclassifications.htm for some specific classifications of ranges. (Below 70 is considered "mild mental retardation" in psychiatric circles, apparently)
