IQClock offers a free timed reasoning test with 30 puzzles and a 25-minute limit. It reports how you did on the puzzles, but gives no IQ number or population percentile.
What does the test include?
The test includes 30 of our own puzzles across matrices, number and letter series, spatial rotation, and logic. You have 25 minutes to work through them, and you can start for free without giving an email address.
After you finish, you can review every answer with its explanation. The explanations let you see how each puzzle works and which answer is correct.
What does the result tell you?
Your result shows correct answers, time used, scores by area, the hardest level solved reliably, a likely range on a retest, and the score you would get by guessing. It describes how you did on these puzzles.
The test gives no IQ number or population percentile. An IQ score ranks someone against a large tested group, and we have not tested such a group for this test. Read how IQ tests work for context on normed scores.
How can you take the test well?
Take the test in a quiet room where you can focus on the puzzles. There is no penalty for guessing, so answer every puzzle; if one slows you down, skip it and return to it later.
When 25 minutes have passed, the clock stops. You can still review your answers and their explanations after the test ends.
Can you retake it or try a shorter version?
For a retest, form B has 30 different puzzles and a 25-minute limit. It gives you a new set of puzzles to try on another attempt.
If you want a shorter session, the quick test has 15 puzzles and a 10-minute limit. It is a separate option from the full test.
