Can anyone explain the difference between the EERM 1st and 2nd editions? Is there any significant difference? I am looking to take the exam April 2015 and am compiling my reference material list to study for and take into the exam. In reading the hundreds of forum threads on the subject it is evident that it is a personal preference. I would like to start with the EERM, but since there is a very large price difference between the two editions I wanted to get the thoughts of those who may have seen both.
