The General Mental Ability (GMA) scale is normative, meaning the score on it is a relative indication on where one individual is compared to other people, or to "what is normal or typical". The scores range from 0 -10.
0-2 are considered lower than average. People with these scores can have a harder time to stay effective in new or complex situations and their behavior tends to be more concrete.
3-6 is considered as an average result.
7-10 are considered as higher than average. People with these scores tend to be quick learners and strong problem solvers, as they can stay effective in new and more complex situations.
