From memory the assessments were almost exactly like the pre guidance material supplied!
But there is more questions and they do ask some things that require you to use the guidance material in a different light, so keep open minded and stay focused, they aren't that hard!
The Pilapts you cannot really study for, it's about your reaction times and the way your brain handles tasks.
Roughly from memory:
-3D man with shapes in hands, your timed and have to identify how many pictures have a square in the right hand for example. (Man will be upside down and back to front in various pictures)
-Puzzle solving. Your given a small picture of part of a puzzle and are shown two puzzles, you're timed and have to decide whether the peice belongs to either puzzle
-Joystick. Keep the cross-hairs in the middle of the box for as much time as you can. The forces on the cross-hairs change all the time to be ready to react quickly but smoothly.
-Fly a 2D aeroplane through 2D squares in the sky. As simple as it sounds! Very sensitive though, easy to overshoot.
Hope that helps slightly?
My course is coming up to the end of phase one now, Jars in march....
