How to say "revise" in Japanese

• 改めるあらためるJLPT N2approx.Common
  ichidan verb, transitive verbCovers revise in the sense of changing something in order to improve or correct it — amending rules, a law, or a plan. The change is deliberate and aimed at making the thing better.
  どうして考かんがえを改あらためたのですか。↗

  What made you change your mind?
• 変えるかえるJLPT N4approx.Common
  ichidan verb, transitive verbThis is simply 'to change'. It covers revise only loosely, with no suggestion of re-examining or improving, so for careful revision of a draft or plan it is seldom the word you want.
• 練り直すねりなおすCommon
  godan verb, transitive verbCovers revise as reworking: taking a plan, draft, or piece of writing and doing it over, polishing the content. Use it when revision means rethinking the content rather than making small corrections.
  この企画きかくはもう一いち度ど想そうを練り直ねりなおせ。↗

  You should rethink this program.

Choose 「改める」 when revising means changing something for the better, 「変える」 when you simply mean changing it, and 「練り直す」 when you go back over a draft or plan and rework it.
