Cognitive skills work together every day. IQScore separates them so you can see where you are strongest.
Working memory
Working memory holds and uses information for a few seconds, for example when you remember a phone number or follow directions. Try the Number Memory Test, the Visual Memory Test, the Sequence Memory Test, the Verbal Memory Test and the Chimp Test.
Processing speed
Processing speed is how quickly you notice something and respond to it. You can measure it with the Reaction Time Test, the Aim Reaction Test and the Stroop Test.
Attention and mental control
Attention and mental control mean focusing on what matters while ignoring distractions and automatic habits. The Attention Span Test measures how steady your focus stays, while the Stroop Test and the Chimp Test put it under pressure.
Reasoning
Reasoning means spotting patterns, following logic and solving new problems. The IQScore Cognitive Assessment covers pattern, number, logical and applied reasoning in 36 questions, and the Pattern Recognition Test focuses on puzzles like those in IQ tests.

Plain-English, research-based guides to what IQ tests measure and what your score really means.
What is an IQ test?
An IQ test, or intelligence quotient test, measures how well you reason, solve problems and learn compared with other people of your age. On standardised tests, the average score is 100. About two-thirds of people score between 85 and 115, and roughly 2 in 100 score 130 or above. Our guide to what an IQ test is explains how professional tests work.
The IQScore cognitive assessment gives you an estimated IQ score based on 36 reasoning questions. It is a quick, free way to explore your strengths and practise, not a replacement for a supervised test given by a psychologist.
What is a cognitive assessment?
A cognitive assessment looks at the mental skills behind everyday thinking, including memory, attention, processing speed and reasoning. Each of our brain games isolates one of these skills, so you can see where you are strongest and track how your performance changes with practice.
How accurate are online IQ tests and brain games?
Online tests are good for curiosity, practice and comparing your own results over time. A short, unsupervised test measures only a narrow slice of thinking, and results can be affected by tiredness, distraction and the device you use. For education, employment or clinical decisions, only a qualified professional can provide a valid assessment. Our guide to whether online IQ tests are accurate covers the research, and our About page explains how we calculate scores.
