one of 2 things are gonna happen to him if he keeps cheating and you sign him off and he passes his practical because he either cheated or got lucky......1. He will crash and kill only himself in actual IMC. 2. He will crash with passengers into a house or school.

Guess who the Feds are gonna ask about his training? and hope they don't see this thread if you sign him off? I'm guessing he also is gonna pencil whip his logbook.
