Question 1

Does the timer keep running if I switch tabs by accident?

Accepted Answer

Yes — the timer reads from performance.now(), which keeps running regardless of tab visibility. When you switch back the displayed time matches actual elapsed time. The chime may be slightly delayed if the audio context was suspended by the browser, but the countdown itself is accurate.

Question 2

Can I save a session and resume it later?

Accepted Answer

No — sessions reset when the page is closed or refreshed. The timer is intentionally simple, with no accounts or persistence. For multi-day exam practice, set the same preset each session and resume from where you stopped on paper.

Question 3

Can I disable the warning chime entirely?

Accepted Answer

Yes — set the warning dropdown to 'No warning', or uncheck the chime box to disable both the warning and end-of-time chime. Useful if you want a fully silent run with only the visual countdown.

Question 4

Is the timer accurate enough for official practice exam conditions?

Accepted Answer

For practice and self-study, yes — accuracy is within milliseconds of the system clock. For official mocks where timing is invigilated, follow the test administrator's clock instead. The timer is for personal practice, not a substitute for proctored exam software.
