Eurocontrol suggested feasttest.com as a preparation tool. And the people who called to invite us for part 2 suggested that we search the internet for prep tools on DART.
Anw, there is no point in arguing about this. All I am saying is that you may have the skills and that practice will improve those skills. You may pass with no practice whatsoever, but with practice you will definitely, in my opinion, achieve better results. On the other hand, if you don't have the skills, no amount of practice could make any difference, so practice or no practice, you will fail.
These are not skills that can be taught. No one can teach you how to fold a cube, you just have to be able to envision it. And since most of us do not have a hobby of folding cubes, practice will improve someone's spatial awareness. I do not agree that "practice makes perfect" but it sure makes "good", "better" and this is what I am aiming for.
