I was in a class of 50+, almost all DECs (3 F/Os I think?), and 3 that I know of didn't make it. Of those 3, one quit because he didn't want to go to remedial training, and the other 2 were let go after IOE.

During my brief career, I have attended flight training with Flight Safety and 2 airlines, and I can tell you this: I have never experienced such disorganized, unstandardized training, anywhere!

However, as mentioned above, my experience with instructors was very positive, as they are all very nice and always willing to help if needed. A stark contrast to my previous airline training experience, 20 years ago.

I hadn't flown in 13 years, a friend of mine in almost 20 years, neither of us had any difficulty getting though training. As long as you study your flows, call-outs and procedures, and your judgement is sound, you will be fine ;-)
