Exam Timer
Exam Timer — One Countdown For The Whole Room
Put the countdown on the front screen and, if students have devices, on theirs too — everyone sees the identical time remaining, which is the whole point of a fair exam clock. Set it to your exam length and share the link before the paper starts.

Anyone opening your link right now sees exactly this.

For exam halls: use the Light board style
Exam halls are often brightly lit, and a dark screen can wash out on a projector under fluorescent lights. Use the Light style toggle above (next to Board and Minimal) for a high-contrast, dark-on-white display built specifically for that. It's the same countdown, just easier to read from the back row.
Common questions
- Yes, if your exam rules permit devices — every device that opens the link shows the identical time remaining. Many exam contexts restrict student devices entirely, in which case display it on the room's front screen only.
- It doesn't matter — the countdown is calculated from the shared deadline in the link, not from the device's own clock, so display accuracy only depends on the device's clock being roughly correct (typically accurate to within a second), not on it being manually set right.
- It's accurate to about a second across every device, since each one counts down independently against the same shared timestamp — the same underlying approach used by any client-side countdown. For extremely high-stakes timing, follow your institution's official exam-clock policy.
