To pass a test or an exam or a challenge easily. For example, your children are taking an exam, you say, ‘Don't you think you should study a bit more, study a bit more, you need to study a bit more’. ‘Oh don't worry dad, don't worry, no don't worry, I'll sail through it, I'll absolutely sail through it.’ Of course, they fail.
