READY
Practising under a clock is the part of exam preparation that most people skip and most people need. Knowing the material and producing it in a fixed hour are separate skills, and only one of them can be learned the night before.
An hour is the default here because it is the most common paper length, but the number matters less than the habit: whatever the real paper is, practise at exactly that length. A practice run with a vague ending teaches vague pacing.
The tip is a pacing rule worth setting before you start. Divide the marks by the minutes (a sixty mark paper in sixty minutes is a mark a minute) and mark the halfway point on the paper itself. When the timer says thirty minutes gone, you should be at mark thirty. That single check catches the classic failure of writing a beautiful first answer and running out of time for four others.
Press F for fullscreen if you want the clock visible without turning your head, and start it the moment you open the paper, not after you have read it.
Yes: add it to the address, like /exam-timer?t=1h30m or ?t=45m. Anything the parser understands works, including 90m and 01:30.
There is no built-in warning, but the readout is large enough to check at a glance, and the last ten seconds are announced for screen readers.
Yes. It stores the exact moment the paper should end and compares that to the clock, so it cannot drift the way a counting timer does.
For a paper you are reading on the same machine this beats fullscreen: the button beside the sound control puts the countdown in a small window that floats over whatever else is open, so the PDF keeps the screen and the clock keeps a corner. Fullscreen is the right choice when the screen is across the room instead. The floating window needs a browser that supports it, so the button is only there where it works.
