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 âaverageâ IQ is by definition 100, so if you score below that you are dumber than average, and above it means smarter than average. 1  50% of IQ scores fall between 90 and 110.  70% of IQ scores fall between 85 and 115.
