Alexander - thats pretty funny about the guy slapping the joysticks really hard - don't see how that would help at all? When we went in the girl told us that the room is right next to the girls toilets so she's asked everyone who goes in there to be really quiet (what do you girls do in there exactly to make so much noise anyways?)
On a side note I noticed that in the joystick tests I was in there for far longer than everyone else. They were all much further ahead of me I noticed at some stages. I don't think this is a bad thing because in many tasks the difficulty increases with each level and you have to see how long you can last.
Jorocketoz - I didn't encounter any trig or triangles but definately brush up on your estimations skills.
