I don't think passing is an issue. It seems easy enough. As long as you know what you're doing, and you do it well, and know what security precautions/pitfalls there are to take, then you should be fine.
I'll even venture and say Weedpacket MIGHT have it, if he's taken it...
I personally haven't taken it, but I'd love for some free practice exams to be put online so you could do them to see how you'd fair. Maybe last years exam could be put up... who knows. I am definately thinking of taking it though...
