The minimum scores for ACT are 18 for Reading Section, 17 for English Section, and 19 for Math Section. The SAT is usually taken in the early fall (October or November) of the senior year. A number of juniors take the test in the late spring (May or June) and take it again in the senior year.
An IQ score of 115 means performance one standard deviation above the median, a score of 85 performance one standard deviation below the median, and so on. Lewis Terman and other early developers of IQ tests noticed that most child IQ scores come out to approximately the same number by either procedure.
The average American IQ ranges between 90 and 100. Individuals with IQ scores between 160 and 165 are considered extraordinary geniuses, and those with scores of 145 to 179 are considered geniuses. A score of 115 to 144 is considered above average, and scores between 85 and 114 are considered average. Keep Learning.
