How to improve reaction time in a reaction time test?
Practice daily, sleep well, warm up your hands, use a wired mouse and high-refresh display, and avoid guessing the signal.
Why did my click count as a foul?
Clicking before the green light or beep is a foul — it prevents guessing and keeps scores honest.
