Before you start

Reasoning, attention and memory across 45 questions.

Forty-five questions across six cognitive dimensions, getting harder as you go. It takes 15 to 25 minutes.

• Work at your own pace. Time is recorded, but being right counts for far more than being fast.
• Some questions show something for a few seconds and ask about it later. Pay attention when that happens.
• No paper, calculator or searching — the result is only useful if it reflects you.

A reasoning assessment for self-knowledge. It is not a clinical IQ test, produces no diagnosis and does not replace assessment by a qualified professional.
