Our latest test came back with the examiner looking a little shaken and pale "No, no, no, this ones failed, no way, terrible..." he told me as he returned to the office.
I asked the student what happened.
"8 our of 10" he told me with a disappointed look on his face."
"What do you mean 8 our of 10? That's not how the testing system works."
"The last two managed to jump out of the way."
