About this test
A general brain test that draws in equal measure from six areas: number series, shape patterns, verbal analogy, applied maths, logic and spatial reasoning.
This is for interest and self-assessment. It is not a substitute for a clinical IQ assessment.
Q. How is the score worked out?
A raw score is built from how many you got right and how long you took, then mapped onto a normal distribution with a mean of 100 and a standard deviation of 15.
Q. What happens if I run out of time?
The test submits itself after fifteen minutes. Anything unanswered counts as wrong.
Q. What is a verbal analogy question?
You are shown a pair such as doctor : hospital = teacher : ? and asked to work out the relationship and fill the blank.
