A reasoning practice score is not the same as an IQ score

If you answer 24 of 30 practice questions correctly, your accuracy is 80%. That calculation describes your performance on that particular set. It does not, by itself, tell you an IQ score or where you rank in the general population.

What the percentage actually contains

The numerator is the number of correct answers and the denominator is the number of scored questions. On the PickAQuiz reasoning practice, the set contains ten numerical, ten logical and ten visual matrix questions. You can inspect each explanation after finishing.

Two people can both score 24 out of 30 while missing different kinds of problems. One might solve every matrix and struggle with conditional reasoning; the other might make calculation errors but handle the logical conditions well. The section scores and explanations provide information that the overall percentage hides.

Why an IQ conversion cannot be invented

A conversion such as “80% means IQ 120” would require evidence that this particular version of the test supports that interpretation. Question difficulty, sample selection, administration conditions, age coverage and the way the score was calibrated all matter. A score label alone does not supply that evidence.

Our original practice set has no population norms or validated IQ conversion. We therefore show accuracy and item explanations. We do not use the percentage to estimate intelligence, issue a recognised certificate or determine suitability for employment. The methodology notes describe that boundary before you start.

Repeating a set changes the task

Suppose you score 18 on the first attempt and 27 on a second attempt after reading every explanation. You have demonstrated better performance on familiar questions. That can reflect useful learning, remembered answers, or both. It does not establish a corresponding change in general ability.

To make the review more informative, explain the rule without looking at the options. For a number sequence, write the differences or the alternating pattern. For a logic item, identify the exact condition that rules out an alternative. For a matrix, describe the shape, position and fill separately. If you can only recall the answer letter, return to the explanation.

Use mistakes to choose the next practice step

Classify each error as a misread condition, an unsupported rule, an arithmetic slip or uncertainty between options. Choose one category to work on, rather than repeatedly chasing a larger overall number. Allow yourself time to check a proposed rule against every completed row or relevant condition.

If you need an assessment for a formal educational, clinical or employment purpose, first find out which assessment and administration conditions the organisation requires. A free practice result should not be presented as an official credential. For personal learning, the immediate goal is narrower and practical: understand how you reached an answer, and improve how you check it.
