Well someone must know what's causing the failure rate, it can't be motivation as the process to get on the course takes a bit of work in the first place. I'm sure the college wants everyone to pass so is it a case of someone's capacity to deal with the actual flow of air traffic and the way someone deals with that, so even with extra tution and hard work that person simply won't make it? Perhaps I'm wrong but it does seem a highly large failure rate and it is making me consider if I want to go through the process of applying only to get chopped if I was on the course. My motivation is there, but that alone won't get my through the course!
