What it measures
Deductive puzzles: given the rules, work out what must follow.
Your score is read against adults generally. The bands below come from the shape of a normal distribution, which is the model the scoring assumes rather than a count from a reference sample. Most people sit in the middle and both ends are rare by definition, so a band is a position in a distribution, not a verdict.
Good uses
- Practice for the logic sections of admissions and selection tests.
- A check on how you handle formal rules under time pressure.
- Seeing where you sit relative to adults generally.
Known limits
- It covers one narrow ability, so it is not a general measure of intelligence.
- An unsupervised online test is not a clinical assessment and is not an IQ certificate.
- Tiredness, interruptions and previous practice all move the score.
