Other forms: revisions
In British English, revision is going over material you have already been taught, before an exam. Revision notes, a revision timetable, three weeks of revision. It is the noun that goes with the British verb revise.
The other sense is universal: a revision is a change made to a document or a figure after looking at it again. A revision of the forecast, the third revision of the draft. American English has only this sense, which is why an American student who says they are doing revision means they are editing something. Note that revision is uncountable in the studying sense and countable in the editing one — a great deal of revision, but four revisions.
1nounrevisionIn British English, study of material already taught, before an exam.

revision is a going over again.
Latin revisio is a looking-again, from revidere — re-, again, plus videre, to see. Both English senses are the same act: going back over something you have already been through once.
