Precious Octa: I was on a waiting list for nearly 4 months back in the days when I did my tests to Eurocontrol - I've already kinda forgot about it, but then one day I've received a call for the second stage... So waiting list is really a waiting list, you've passed the first phase, but there were better candidates than you, they go first to the second stage tests. As soon as they need you they'll call you, don't worry!
Good luck!
