These ask you to work something out rather than to describe yourself, so unlike the personality measures they have right and wrong answers. Some sample a single kind of reasoning, such as spotting the rule behind a sequence of figures; others spread across several, mixing verbal, numerical and spatial material.
A score reflects how you performed on this occasion, on these particular items, against adults generally. It is not an IQ in the clinical sense: that requires an individually administered test given by a qualified psychologist, under controlled conditions, and nothing taken online is a substitute for it.
