I had a very bossy sim buddy once. For the first few sims I was not up to his level but by sim 4 we were both about the same (according to the instructor). He felt he needed to coach me on everything from programming the box to flying the missed.
He paid for seat support as he felt I was a liability to his check ride. We both turned up at the same time on test day and he went first. He managed to bust his check ride in less than 30 mins and I went in and passed.
