Go the extra mile
‘Go the extra mile’ means ‘make a special effort’ or ‘work really hard (harder than usual)’. It is a positive comment about someone’s effort (usually work). In the US (and in the UK in the past) people use miles, not kilometres. A mile is about 1.6 km (kilometres). So if you drive an extra mile, you go a little bit further. If you go the extra mile, you work a little bit harder. For example, ‘James really went the extra mile to prepare a great dinner party. He even hired a musician’.
A: Hey, are you ready for the test?

A: Wow, you really went the extra mile.
Have you ever gone the extra mile for a project at school or at work?
