I will be taking power PE exam on April 2019. Thanks for the insight.
You're welcome. Hopefully I won't be taking it with you. Best of luck to you either way. I received my degree in ME and been doing electrical design pretty much ever since (although I spent 2-1/2 years in EE before switching majors to ME, so I had
some EE background). You're going to find a variety of responses as to best methods of studying and what resources to use. I highly recommend going to Zach Stone's website. He has some free articles you should definitely check out IMMEDIATELY, most notably "Recommended References for the Electrical Power PE Exam" and "What do Successful Engineers that Pass the Electrical PE Exam Have in Common?" If you can afford it and/or get your company to help pay for it, I highly recommend his course. If I had to do it over again, knowing what I know now, I would:
1. You have just less than 7 months until the April exam. You might think that's plenty of time but you'll be surpised how quickly the exam date approaches. Use your time wisely.
2. I would start with the NCEES practice exam, and go through and work EVERY problem between now and the next 1-2 weeks. Don't spend much time pouring over the problems. In other words, don't spend 1-2 hours on one problem. You're not going to have a clue on half of them right now, so just work through them, use the solutions or go online (lots of explanations on this board) and just write out EVERY problem and work them out on separate pieces of paper (keep your practice exam tests blank for future timed practice exams). Trust me. You just want to get an immediate feel for how long these problems take, the wording, the language, the material/topics, ect. Just don't stress and get stuck. You don't want to get to 2 months before the exam and you've spent so much time on other stuff you haven't yet worked out some of these problems.
3. By December you should have at least had worked out all the practice exam problems (even better if you use mutliple sources, . Make a list of topics you struggle on. NEC and protection should be a priority regardless since those topics weigh heavily on the exam.
4. I really wish I had done this sooner: I took Zach Stone's online course. Once a week it's a 3-4 hour live webinar. After each lesson he gives you homework problems relating to the course. I spent a lot of time doing those and they really helped, but it became apparent that I would have done better if I made myself go through the online course for the related topic leading to the live webinar. For example, if "Rotating Machines" was going to be the live class for Tuesday, I should have at MINIMUM gone through the rotating machines articles and quizzes. Instead I was working through NCEES sample exam problems, or problems from another resource, or taking timed tests, which is fine, but I should have made sure I went through the courses and quizzes. I would have absorbed the information better. Once I started doing this my learning curve shortened.
5. Take timed practice exams sooner, and more often. I observed a lot of people taking their first timed practice exam (if at all), 1-2 months before the exam. I took 4 timed tests (2 NCEES, 1 Graffeo and 1 Eng Pro Guides). I didn't really do all that well on any of them, but I'm glad I did them and wish I had taken the time to do more. Time is simply not on your side, especially when you have a family, so use your time wisely.
6. As good as Zach's class is, you're still going to have topics you struggle with. Don't get stuck. Go to YouTube videos or this board to get information or a different perspective on how to approach problems. Everyone thinks and learns differently.
