Good job to those who passed. I've been out of school for 7.5 years and I had to re-study completely from scratch. I remembered nothing when starting to study for the PE exam 6 months prior to. EERM is a useful book but one should not rely on it solely to pass the exam. I would say about 20% of the questions can be directly answered using EERM and there were a few areas where I feel the book is wrong and needs revisions. The exam deliberately asks questions that are not easily answered unless you have a specific subject matter book so it kinda forces you to bring other references as well. Go as comprehensive as you can as deep as you can. I bought a bunch of Schaum's books too but I hardly opened them except for communication parts where I needed extra practicing.
