The IQ practice test uses 15 questions covering number series, verbal analogies, and pattern recognition — the same formats used in real intelligence assessments. You have 20 minutes. Scores are for practice only, not a certified IQ measure.

How IQ Tests Work
IQ (Intelligence Quotient) tests measure cognitive ability relative to a population. A score of 100 is average by definition — about 68% of people score between 85 and 115. Modern IQ assessments like the WAIS-IV and Stanford-Binet test multiple cognitive domains including working memory, processing speed, verbal comprehension, and perceptual reasoning.
Question types used in this test
Number series questions measure abstract reasoning and numerical pattern recognition. Verbal analogy questions (A:B :: C:?) test vocabulary depth and relational thinking. Both types appear consistently on Mensa admission tests, the SAT, and cognitive assessments used in hiring.
Can you improve your IQ score?
Fluid intelligence (the raw ability to solve novel problems) has a strong genetic component and changes little with practice. However, familiarity with question formats substantially improves test performance. Practicing number series and analogies for 30 minutes before a real cognitive assessment can raise scores by 5-10 points purely through reduced test anxiety and format familiarity.
FAQ
Is this a real IQ test?
No — this is a practice test inspired by the types of questions used in cognitive assessments. It's useful for familiarizing yourself with IQ-style question formats, but it cannot produce a certified IQ score. Official IQ testing requires a licensed psychologist.
How many questions are in this test?
There are 15 questions covering number series, verbal analogies, and pattern recognition. The full test should take 10-15 minutes if you work at a normal pace.
Is there a time limit?
Yes, 20 minutes total. A countdown timer is shown. Most people finish well within the limit — the timer is there to add a bit of pressure, which better mimics real IQ test conditions.
What do the scores mean?
A perfect score of 15/15 puts you in the top tier for this test's difficulty calibration. Below 9 is below average. These are rough estimates only — question difficulty on this test is not clinically calibrated.
What types of questions are included?
Three types: number series (find the next number in the sequence), verbal analogies (A is to B as C is to ?), and pattern-based reasoning questions. These are common formats on standardized intelligence assessments.
