The CTP course has very specific subject matter to be covered in both the ground school and simulator portions. I can't speak much to the ground school b/c I wasn't involved with that. I did however participate in the designing of the 10 hour simulator curriculum for AWAC. It had ZERO to do with the ATP written exam. I'm going to guess that the ground school portion deals more with broad/general subject matter pertaining to turbojet/prop aircraft and performance and is not designed to actually prepare you for the written exam. I'm sure someone else here can speak from either experience or knowledge of that syllabus.
