Practice Lab is an entertainment and educational activity. It is not a clinical, diagnostic, standardized, or professionally recognized intelligence assessment. Practice items never count as unseen scored Novus Reasoning Challenge form questions. Your practice results are not an IQ score and cannot be used for Mensa qualification, diagnosis, giftedness identification, educational placement, employment selection, disability applications, accommodations, legal matters, or medical decisions.
Untimed instructional practice for the Novus Reasoning Challenge. Explanations teach the reasoning process. These items are not unseen scored-form questions and do not produce an IQ score.
