How It Connects
Typing Speed Trainer is a web-based productivity application measuring typing speed (WPM), character accuracy, error distribution, and backspace counts in real-time. Features dynamic paragraph generation and instant visual feedback on mistyped keystrokes.

How It Works
Test Initiation
User presses the first character; timer starts automatically.
Score Calculation
Computes gross WPM, net WPM (penalizing errors), and accuracy percentage.
