I am with Ishi, I have only had normal experiences with the ANA instructional staff, in fact I think that they have put in more effort than a western counter part.
We currently do long tours through north America, so the team has to be reasonably friendly to each other.
It does seem that there is a high failure rate right now, a whole course of AJX was wiped out a week or two ago. Hang in there Lear and remember the ANA insructor is busting his gut to get you through, a loss of a candidate is also a loss of face for an ANA instructor.
