With adults the concept has become a commonly used method in
relation to e.g. military drafting sessions and general
employment procedures, but it is also used for assessing brain
damage, etc. Furthermore, there are societies for people with a
particularly high IQ of which Mensa (the top 2% of te
population) is probably the best known. In adults the IQ is
calculated on the basis of known 'normal' level. The median
value is set a 100 and the normal ranges from 90 to 110. The

has an IQ below 100. The level of difficulty of the questions
