Gray matter refers to components of the central nervous system. Its purpose is to send motor stimulus around the body to the brain. According to a number of studies and tests, the amount and location of gray matter tissue in the brain is closely linked to human intelligence. This was concluded after comparing the studies collecting structural images of the brain as well as IQ tests from the same people. It was found that those with more gray matter in certain areas of the brain received better scores on the IQ test. It was also found in a similar study that IQ scores are closely linked to the structure of the cortex.
IQ is defined as a general measure of a person's intelligence by ranking them in comparison with all others. A regular IQ test is written with questions that test your short-term memory, verbal knowledge, spatial visualization, and perceptual speed. They are designed to test the speed at which you can react as well as the level at which you can answer problem solving questions. The idea of an IQ test structure is to test an individual's intelligence rather than their general knowledge. It is because of this that it can be criticized by some. Other methods that are believed more efficient at measuring intelligence are the ability to retain and apply knowledge. However a test such as this would be bias towards those who have had the privilege of a better education.

The personal importance of knowing your IQ test has always been high. This can be mainly due to the amount of positive attributes related to people with high IQ's in society . Studies have shown tendencies for people with higher IQ's to have better job performance, higher incomes and more of a probability to achieve great things. This last attribute is skewed by the conclusion that those with lower IQ's have more of a change of committing a criminal offense.
Since early days of IQ tests, which were over one hundred years ago, the average IQ score has been increasing by 3 points every decade. Although this may be because of improved education, many believe that modern education has been more and more directed at IQ. Inconclusive tests point towards improved nutrition as the cause for this increase.
Probably the most beneficial way to improve your IQ score is to read. A big proportion of the test requires reading and comprehension and the best way to increase your speed in doing this is to read as much as possible. Another big part of the test is logic and problem solving. These skills can be improved by doing crosswords or by playing Sudoku, chess and other similar games. And as always, it is important to eat and exercise properly in order to give your body and brain strength. Unfortunately, the method that results in the most dramatic increase in IQ results is to age. It has become clear that as a person gets older their IQ tends to increase by about 10 points in some cases. This is unfortunate because we have no control over this. So the best way to improve IQ is to get older.
There are a number of ways to access these tests; however the easiest way nowadays is online. Normally it costs about $10 to take a test but I have found a website with a free test that is of good standard. So if you would like to know how intelligent you are compared to your friends and family, have a look at the link I have posted below.
