One use of IQ scores has been helps identify individuals with metal retardation. Mental retardation refers to a substantial limitation in present functioning that is characterized by significantly sub average intellectual functioning, along with related limitations in two of ten areas, including communications, self care, home living, social skills and safety.
    Psychologist caution against using IQ scores as a sole test of mental retardation. IQ test are usually used in combination with observation of adaptive skills, which include social, home living and communication skills. On the basis of IQ scores and adaptive skills, three levels of retardation have been identified.
1. Borderline Mentally Retarded – these individuals have IQ that range from 50 to 75. With special training and education opportunities, they can learn to read and write, gain social competency, master simple occupational skills, and become self-supporting members of society. About 70% of individuals with retardation are in this category.
2. Mildly/moderately mentally retarded – These individuals have IQs that range from 35 to 50. With special training and education opportunities, they can learn to become partially independent in their everyday lives, provided they are in the family or self-help setting.
3. Severely/profoundly mentally retarded – these individuals have IQs range from 20-40. With special training and education opportunities, they can acquire limited skills in taking care of their personal needs. However, because of retarded motor and verbal abilities, they require considerable supervision their entire lives

Rajan, Mahadevan stood before the packed house of the International Congress on Yoga and Medication. He recited, from memory, the first 31, 811 digits of pi, which is often rounded off to two decimal places, or 3.14. He did not err until the 31,812th digit. This feat took 3 hours and 44 minutes and earned him a place in Guinness Book of World Records. Researches Charles Thompson discovered that Rajan can quickly recall the digit at any location with the first 10, 000 digits pi. This would be equivalent to memorizing the names of 10, 000 people seated in a number seats and then recalling thr name of any single person, such as the one sitting in seat 2, 141. Rajan can repeat a string of 60 numbers after a single hearing, while most of can repeat about 7-10 numbers. Rajan is one of the half dozen people worldwide with such gargantuan memory powers.
Despite Rajan’s unbelievable ability to memorized numbers, he seems to be worse than average at recalling faces, and he constantly forgets where he puts his keys. Rajan’s pi record has since been broken by Hiyoroki Goto, who correctly repeated 42, 195 digits of pi in 9 hours.
No one questions the accuracy of Goto’s memories because they can be verified. However, some memories are not so easily verified, as in the case of Holly and her accused father.
