Hi Zay!
You can't prepare
, the only thing you can improve is the English !
Each task will be told very clearly,you will know what to do,but the english is needed because you have to understand the exercises perfectly and a long story in english.wich contains different accents.
Maybe you can prepare a bit with the help of this game for the ball on the wall test:
Multitask - Play it on Not Doppler
And the other one is the cube test,you can draw cubes folded and unfoldeld way.
After all you have to prove in 6 abilities,and if you fail one of them you are out
Best of luck Zay.
