15 Minute Revision Timer — Free Online Countdown

Why a 15 minute revision timer works

Spaced passes over re-reading
Cover the notes and recall aloud
Rotate subjects between blocks

Spaced passes beat one long re-read, because the gap between them is what forces genuine retrieval. Rotate subjects between blocks rather than staying on one.

Questions people ask

How many revision blocks should I do in one evening?

Four to six fifteen minute blocks with five minute breaks is a full evening's revision for most students, and it holds attention better than two long sittings.

Is it better to study in short or long blocks?

Short blocks spread across days beat one long session for recall, because the gaps force your memory to retrieve rather than recognise.

How often should I use the 15 minute revision timer?

Daily beats long. Three short sessions spread across the week produce better recall than one session of the same total length, because the gaps force your memory to retrieve rather than recognise.
