The loading of the quiz during the selection process is about 10%. Do not overheat your brain on the quiz - rather have a good look around you and decide if you want to live in the dessert!
The EK selection process has one aim and one aim only -
CAN THIS INDIVIDUAL LIVE IN THE DESSERT?
If you are married then the question becomes -
CAN THIS INDIVIDUAL'S WIFE LIVE IN THE DESSERT?
THAT IS WHAT IT IS ALL ABOUT MY FRIEND!
