Questions
Are these tests free?
Yes. Every test is free and unlimited, with your score and percentile.
How accurate are online reaction time tests?
They measure you plus your device. Screens, mice and touchscreens add roughly 20 to 80 milliseconds. MindSpeed compares results only within the same kind of device and explains the method openly.
What is a cognitive profile?
After three or more tests, MindSpeed combines your best results into five skills: speed, visual memory, working memory, verbal memory and typing. Each is shown as a percentile.
Do I need an account?
No. Results are saved in your browser. With a free account they are kept on every device and in the app, and you can sign in with the same account as IQ Test Coach.
Is this a medical or IQ test?
No. These are short self-tests for fun and self-tracking. They are not a diagnosis and not an IQ score.
How are percentiles calculated?
Against recent valid results of the same test on the same kind of device. Until a test has enough results, published reference values are used, and the page tells you which.
