Using the exam clock in an exam room

Enter the exam name, start time and length. Add reading time if the paper has it.
Type the rules you want on screen, for example "Phones off", "Write in black ink".
Press Full screen on the projector or display. The screen stays on while the exam runs, on browsers that allow it.
If the exam starts late, press Start now. Extra time for a candidate or a disruption? Press +5 minutes.

The time comes from the computer's clock, so check it against the exact time before candidates arrive. For a simple countdown, try the classroom timer; for a clock to teach reading the time, use the teaching clock.
