StartHow to get more consistent results
Reaction and click-speed results can be affected by refresh rate, touch latency, mouse hardware, and browser load. Repeat tests on the same device to understand your trend.
Memory and focus tests reflect your current state. A quiet environment and a rested mind usually produce more consistent results than a distracted session.
