Sounds like he needs to learn how to be a private pilot first. Not everyone can get all their ratings in 100 hours. He may very well turn out to be a good all around pilot but it sounds like he is way behind the aircraft. He sure seems overwhelmed at this point.

Unfortunately for professional pilots.....Wannabes get to play on our playing field. If you don't think he is ready, don't sign him off. He will be flying in our airspace.
