About Mensa IQ Test-4
What is the difference between this version and the previous three versions?
This version has larger questions and longer time. It emphasizes multi-step rules, quantity planning and spatial integration, and pays more attention to sustained concentration and complex information processing.
Can I join Mensa if I reach a high percentile?
cannot. The percentiles on this site do not use Mensa-approved surveillance tests or population norms and can only be used as an internal reference for this exercise.
What should I do if I encounter difficulties along the way?
Mark and skip first to ensure you can complete more confident questions; finally use the remaining time to deal with difficult problems that require multi-step reasoning.
