MensaIQ

MensaIQ is an online cognitive assessment service for people curious about how they reason and where their strengths lie. Its free IQ-style test includes 40 questions across five domains: pattern recognition, logical reasoning, spatial reasoning, numerical reasoning and verbal reasoning. The assessment takes about 25 minutes and uses adaptive pacing to adjust the order of questions while including every response in the final score. After completing the test, users can unlock a report with an overall IQ-style score, percentile, domain-by-domain results and plain-language suggestions for what to train next. A sample report is available to preview.

MensaIQ explains its scoring approach and the limits of its results: scores are converted to a scale centered on 100, but the assessment is intended for educational and entertainment purposes, not as a clinical evaluation or diagnosis. The site also offers brain games, puzzles and training courses to help users keep their minds active.
