IQ stands for intelligence quotient. Supposedly, an IQ score tells one how “bright” a person is compared to other people. The average IQ is by definition 100; scores above 100 indicate a higher than average IQ and scores below 100 indicate a lower that average IQ. Theoretically, scores can range any amount below or above 100, but in practice they do not meaningfully go much below 50 or above 150.
Half of the population have IQ’s of between 90 and 110, while 25 percent have higher IQ’s and 25 percent have lower IQ’s:

In 1987 Dr Wynand de Wet did his practical research for a Master’s degree in Educational Psychology at a school for the deaf. The subject of his research project concerned the optimisation of intelligence. The group who did Edublox were tutored simultaneously for 27.5 hours between April and August of that year, and showed an increase of 11.625 in non-verbal IQ scores, from an average of 101.125 to an average of 112.75. The group who did not receive cognitive training showed an increase of 4.625, from an average of 104.25 to an average of 108.875.
Our own trials confirmed that Edublox increases IQ scores. In one experiment the IQs of ten youngsters with severe learning difficulties were tested before starting on the program, and again after receiving 40 hours of one-on-one instruction. Their ages were between 7 and 18. The mean verbal IQ score increased from 85.4 to 91.0, the mean non-verbal IQ score from 92.6 to 105.1, and the mean full scale IQ from 87.0 to 97.1.
The increases in verbal, non-verbal and full scale IQ were highly significant according to the two-tailed t-test.
