Getting your lessons ready
Request a focused correction using the full source and reply, then check the entire result.

If most of a reply is right, ask for a focused edit. Give the full reply and the source words that show the mistake.
You do not have to fix only one thing when several parts are wrong. Name all needed changes, or start again if the reply is about the wrong task.

A clear correction gives you something specific to check.
