After doing some searches online, I was a bit surprised to find very little on the IEDC CEDC examination. I'll be taking the exam and I'm looking for insight and ideas as to its composition and level of detail. I'm having trouble determining how much detail to really study, given the broad topics covered by the exam and the field. In short, how much detail is expected in the essays and oral interview? With pass rates of 38% and 48% the last two years, the difficulty of this certification appears to be above average - why?
