Other forms: revised, revising, revises
To revise is to look at something again and change it — a draft, a plan, an estimate, an opinion. Revised figures, a revised edition, revise your expectations downwards.
British English has a second, very common sense that American English does not: to revise for an exam means to study material you have already been taught. An American student reviews or studies; a British one revises, and revision is the noun for it. That difference causes real confusion, because revision in American English means only the changing of a text. Note that revise is not the same as review: reviewing is looking at something to judge it, revising is changing it.

Latin revisere is re-, again, plus visere, to look at carefully — itself from videre, to see. To revise is to go back and look again, which is exactly what both the British and the American senses ask you to do.
