Here's a summary of my PE experience
Studying: I took the PPI2Pass on-demand course (books plus recorded lectures). I found the practice material to be very helpful and there was a lot of it, which played a roll in passing. I did diagnostic quizzes, content quizzes, book practice problems, quizzes in my weak areas, and took their practice exams a few times. I always had the NCEES reference handbook up during study to get comfortable with it. Their recorded lecture were helpful to provide another way to cover material. I used the 1.25x speed player options since the instructor talked a bit slow. This helped knock out each 3-hr lecture faster. Total hours spent preparing/studying = 186. I also realized the week before my test that I was never sent the PPI2Pass printed practice exams book...
Test Experience: I found the test to have more qualitative problems on it than expected. It was also more similar to the PPI2Pass Online Practice Exams vs. the NCEES Practice Exam booklet. I was not able to "ctrl+F" search on my test, and had to click the search button each time. Also, you cannot hit enter to view the next search term, you have to select each one. This wasnt expected and took a minute to get used to. During the test, my keyboard stopped working and I was asked to leave the room while my computer was shutoff and rebooted. This was pretty nervewracking and I am happy that I passed or else I would question the validity of the test and lost time. I finished the morning section with a few minutes to spare, and finished the afternoon section with 45mins left. Bring snacks/coffee and take a quick unscheduled break if you are good on time and hit a wall. Cough drops are the only food allowed in the test room, so bring a few of them to keep your energy level up (sugar).
Advice: Put genuine time into studying. When you are taking the test, accept that you wont know the answer to all questions and move on.
