For the reasons that I stated in my prior post. If I need to go into the program with the knowledge already, what is the point? I have a good FBO so I don't see the frustrations as being an issue with going to them. I knew who my DE would be, so I could study from the gouges from his checkrides. I heard from many people who have gone to ATP that they get you the certificate, but don't make you ready to instruct. Even though ATP has fixed costs, I got done for less money at my FBO. I had a lot of reasons, these are just a few.
