Sharpclassic has a point. I researched to a similar level of detail to that mentioned above, spent hours and hours preparing. Turned out I could have got away with next to nothing. A few easy personality based questions and couple of very straight forward questions about which types ezy use (which is common knowledge). This was a few months back, I get the impression it was tougher in the past, but pretty straight forward when I went through. And now you don't even have to have the sim check either!!
