Oooops - saw this a bit late. Basically, computer game skills will get you through! All done in front of a screen in about two hours.
A bit of a number memory test, some spatial orientation tests, mechanical skills (keep the ball in the circle type tests), usual sort of stuff.
They say that you can't practice for it though, i.e. the program is sophisticated enough to assess your current skill level and adjust itself accordingly. Don't know if that's true or if they are just trying to pysch you out.
Just stay sober, get some sleep and pop those ProPlus. Stay frosty! Good luck.
