Stopwatch

Stopwatch measures how much time has passed since you started. Choose it when you want to learn how long a task takes, without setting a deadline first.

Use it for exercise practice, reading or revision. The goal is to understand your pace, not to rush every task.

Decide which activity you want to measure.

1. Start the stopwatch when you begin studying.
2. Add a checkpoint when you finish an exercise or move to another part of the lesson. Pause if you stop working.
3. Pause at the end and review the timing. Reset only when you are ready to begin a new measurement.

Checkpoints mark moments in the same session without restarting the stopwatch. They help you compare different stages of your work and find where you spent more time.

Use fullscreen for a clear timing display, or quick access to keep the stopwatch available while using other study material.

Time a few similar exercises, then look at the differences. A question that took longer may need more practice, but it may also be more complex than the others.

Use your observations to choose realistic durations for future sessions. Compare similar tasks and account for interruptions before judging whether your pace has changed.

You can open the Stopwatch without signing in. Use its start, pause and reset controls to manage the measurement while you study.

Pause when you take a break if you want to measure active work only. Keep the tool available and review your checkpoints before resetting the session.
