Revision timer

How to use the online timer

Twenty minutes is a revision block rather than a study block, and the difference matters. Revision is going back over material already met once, which means it should be quick, uncomfortable and mostly done from memory. Twenty minutes is enough for one topic done that way, and short enough to fit several into an evening in the fortnight before an exam.

Pick the topic before starting and work without the notes in front of you: write down what you remember, then check. The gaps that turn up are the whole point of the exercise. The count runs inside this browser tab, so keep the page open behind whatever you are writing on, since closing it ends the block without any announcement.

Revisiting a topic several times across a fortnight fixes it far better than going over it four times in one night, even though the single long session feels more like work. Spacing the blocks out and mixing subjects between them is harder in the moment and easier at the end, which is an awkward trade to accept while sitting at a desk in April.

Common questions

How is revision different from studying?

Revision goes back over material already met once, which means working from memory rather than from the page. Twenty minutes without the notes in front of you finds gaps that rereading never will.

Is it better to do several short blocks or one long one?

Several, spread across days. Revisiting a topic four times over a fortnight fixes it far better than four passes in one evening, even though the long evening feels more like effort.
