There is so much information to learn to truly know and understand deeply, that I don't see how anyone could ever be successful coming from a 2-week wonder course.
The Flight Instructor Certificate is frustrating and painful af! It's not a fun certificate to pick up at all. Sometimes I wish I had never started down this path, but I'm not a quitter and I'm not stopping until I pass my checkride. Hopefully this misery will all end this spring and teaching will be better than getting beat up by my instructor all the time.
