Hello everyone,
I passed the PE exam earlier this year! I got a little busy but finally got around to writing up this success story. While studying for the exam I would often read success stories on here so I thought I should share what I did to prepare for the exam.
I bought Zach Stone's Electrical PE Review unlimited package in September of 2025, and started studying by watching and completing all of the videos and homework. I watched all videos at 2x speed, unless there was something that I really didn’t understand I would watch it at 1x.
After completing all of the on-demand and live class videos, I started doing a bunch of practice problems from all different sources, essentially as many practice problems as I could. Then I started adding in timed practice exams, I did a bunch of practice exams.
From September to February I studied everyday for at least 2 hours during the weekdays and at least 8 hours on Saturday and on Sunday. I pretty much didn’t do anything for these 5 months except work, study and go to the gym. Even at the gym I would watch videos related to PE exam material.

I did the TSG, AIT, QPP and NCEES practice exams multiple times, I basically memorized the NCEES exams from reviewing them so much.
I think the Electrical PE Review exams are pretty much on par with what I saw on the actual exam, maybe slightly harder. I would say the exam felt like 70% TSG/AIT/QPP and 30% NCEES practice exam in terms of difficulty (to me the NCEES practice exams seemed easier than the actual exam).
The Complex Imaginary exams seemed WAY too easy so I just did them as extra practice problems. I personally wouldn’t recommend them unless you’re able to get them for free.
Engineering Pro Guides was also very good in terms of matching difficulty of actual exam, I would definitely recommend the exam #3 if you’re not comfortable with the code sections. You should expect the actual exam to have a lot of code questions so it’s good to be comfortable with all of the codes and standards.
Out of all the study materials I used, Electrical PE Review was by far the best because it gave me a solid foundation to solve all other problems from third party sources so I’m very glad that I invested in it.
Exam day and after
Going into the exam I felt very confident but it definitely gave me a run for my money and I left feeling it could go either way. The exam honestly felt hard for me, but in retrospect I think it was just because of the testing environment. I took four hours on the first section and four hours on the second section. The first half felt pretty challenging and there were plenty of questions that I wasn’t 100% sure on so I made my best guess and moved on. At the 4 hour mark I reluctantly took my break knowing that I should save a solid 4 hours for the second half. Luckily, the second half seemed much easier to me. I started the second half knowing exactly how to solve almost every question, I felt so much more confident in the second half than the first. There were still some questions that I wasn’t 100% sure about but not nearly as much as the first half. Overall, I left the exam thinking I had a fair shot but then I started checking the answers to a few questions that I guessed on and I realized I got them wrong, so I stopped checking. Another thing I noticed about the exam was that I couldn’t really tell which questions were pretest questions. I took my exam on Monday 2/9 and had to wait until the next Wednesday 2/18 to get my results. During that time I essentially hoped for the best and prepared for the worst, keeping all my study material handy just in case. Thankfully, I received a pass notification!
Based on all the material I used I probably did close to 2,000 practice problems, and probably closer to 3,000 if you count the problems I did more than once. This might seem like overkill and to be honest it probably is but I tried to expose myself to as many different types of problems as possible because I really didn't want to take this exam more than once.

Hope this information helps you guys, you got this!
Also here’s a small tip, engineering economics is NOT tested! Read every question carefully!
