IQClock’s quick test is a free, timed set of reasoning puzzles for a brief practice session. It lets you review your answers and performance, but it does not report an IQ score.
What the quick test is for
This test is a short, timed sample of reasoning puzzles for anyone who wants a focused session. It has 15 puzzles and a 10-minute limit, and you can review every answer with its explanation.
Use it to try the test format or see how you handle a brief timed session. It is free, requires no sign-up or email, and nothing is paid at the end. For untimed examples, try the practice puzzles.
Why the shorter test gives a wider likely range
A shorter test gives a wider likely range on a retest because fewer puzzles provide less evidence about how consistently you solve different kinds of problems. A small set can be more affected by which puzzles appear and how you approach them.
That range describes uncertainty across attempts. A longer test provides more puzzles across reasoning areas, giving a broader basis for comparison. See how results are calculated on the methodology page.
What your quick test result shows
Your result shows correct answers, time used, the likely range on a retest, the score you would get by guessing, the hardest level solved reliably, and your score in each area. These details describe your performance on this attempt.
IQClock does not print an IQ number or population percentile because an IQ is a rank against a large tested group, and IQClock has not tested such a group.
When to take the full test instead
Take the full test when you want a broader sample of your reasoning across more puzzles. It has 30 puzzles and a 25-minute limit, so it suits a longer session.
Choose the quick test for a shorter session. Choose the full version when you have more time to answer questions before reviewing your results.
