02 — What is here
Inside a free IQ test online
Every quiz on this page runs in the browser, scores instantly, and puts you on a percentile against everyone else who has taken it. Here is what each family of quizzes actually asks your brain to do.
These are IQ-style and cognitive quizzes, not exams. You answer, you get a score, you see where you sit against other anonymous players, and you leave. Nothing costs money and nothing asks for an email.
Results are not clinically validated and should not be used as a substitute for professional assessment.
IQ-style quizzes. The IQ Test is the long form and asks you to hold several rules in your head at once. The Quick IQ Test is the same idea in a hurry. The Pattern Recognition Test strips out language and leaves you with shapes and sequences. The Cognitive Abilities Profile spreads its questions across a few kinds of thinking instead of hammering one.
Wider cognitive quizzes. Logical Reasoning is about following an argument to the only answer it allows. Problem Solving hands you a situation with more than one route through it. Spatial Reasoning asks you to turn objects over in your head. Emotional Intelligence reads people rather than shapes. The Full Cognitive Assessment covers the lot in one sitting, and the Cognitive Age Test reports your result as an age band rather than a number out of 100.
Memory quizzes and drills. The Memory Loss and Short-Term Memory quizzes are questionnaire style, so they ask about everyday slips. Visual Memory and the Complete Memory Profile test recall directly. When you want raw practice instead of a quiz, the timed drills are Number Memory, Sequence Memory, Verbal Memory and Backward Span, each scored in its own units so a retest actually means something.
Personality and lifestyle. If you came here for a different sort of self-check, the Personality Type Test, the Brain Fog Test and the Sleep Quality Test sit alongside the IQ ones. Sleep and fog answers often explain a middling score better than ability ever will.
03 — How ranking works
Scored, then placed on a percentile
Each quiz is scored in its own units first, then compared with every other anonymous attempt to give you a percentile. Nothing here is graded against a clinical norm. The scoring page sets out the Brain Score, the five domains and what 100 means.
A low score is a starting point
One bad run tells you very little. Tired, rushed or distracted shows up in a score long before ability does.
