Intelligence is defined at the ability to learn, understand and make judgments or have opinions that are based on reason. Being intelligent means having the ability to acquire and use knowledge for solving problems and adapting to the world. IQ is simply the unit of measure for expressing the results of intelligence tests. Specifically, IQ is the ratio of a subject’s mental age (as determined by their performance on an intelligence scale) and chronological age. There are many types of intelligence, but only standard IQ predicts your success at school and in work. In fact people with higher IQ scores complete more years in school and have higher status jobs. Recent research has also found that people with higher IQs are also happier and healthier. While you do not need to have a high IQ for its own sake, improving your intellectual ability will help you deal more effectively with school and work challenges, as well as make decisions and solve everyday problems more easily.
