Ah I see what you’re getting at.

I “failed” my first test, because I showed up and my car didn’t have a warrant (it was warrantable, just had missed a reminder).

Is it semantics, though? I guess when they say X number of people failed their test then you need to take that into account. But I don’t think there is any impact on the person, there’s no penalty for a fail other than the cost - and that’s now gone with free resits.
