Exam cues
Sound and warning cues stay secondary to the exam countdown.
Custom duration
Exam Timer (Fullscreen Countdown)
Run timed practice with a calm fullscreen countdown, presets, optional warning beeps, and keyboard shortcuts.
Configure a timed section
Choose a minute preset or enter a custom duration. Optional warning controls can mark the five-minute and one-minute points. Final beeps apply only to the last seconds when enabled.
For a 25-minute practice section, choose 25 minutes and enable both warnings. Pause stops the current countdown without clearing it. Reset returns to 25:00 and restores the warning schedule for a new attempt.
Use limits
This is a browser timer, not an exam administration system. It does not lock the device, collect answers, or keep an attempt record. Fullscreen only changes the display. Keep the page open because device sleep can delay warnings and completion audio.
