Agreed. The School of PE provides excellent notes and solved problems for taking the PE Power Exam. When I took the course the instructor was a joke, the only section he did reasonably well was the Codes which is important so he did help me somewhat. You have to study the notes and create a binder of the important pages. The owner did an excellent job on the engineering economics...get those easy questions. This was my main resource for the exam. I also had Camera which helped minimally. Of course, you have to get the codes books and know how to use them. The NCEES practice exam is a must...take your time to do and understand the questions, many similar questions appear in the exam. DO NOT bring too much materials to the exam. Use tabs and know where to find stuff in seconds.
I passed on my first attempt even though my EE major was in electronics. I work in a Power environment so that's why I too the PE Power. Don't under-rate the exam, study hard with exam day in mind so you could know which stuff to bookmark. Tabs are your best friend during the exam. GOOD LUCK!
BTW did anyone figure the cut off score for the April 2018 exam? The highest I saw was a 49 that failed. It has to be a higher score than that.
