once you pass the admission procedures and assessments, you should expect the guys there to support you up until the end
Do they need to keep a minimum graduation ratio to keep their FTO approval ?
If it's like in Europe they can still refuse to let you do the exams if you're not good enough, and you'd still have paid the money. As such I don't see the point of screenings and assessments, they need to make money it's not a charity school.
