This was my first time taking it (April 2019) after being out of school for roughly 28 years. My work experience is 100% on the Utility side of Power, so no prior background with NEC. My personal take is that the morning session was rougher than the afternoon, but maybe we don't all get these in the same order. Did not manage my time well on the AM session, but finished early on the Afternoon session and had time to go back and review. Hopefully, that balances out. I think they far exceeded their published percentage of NEC-related questions on this exam, but that's not all bad, if you learn where to look. I'm curious if anyone else feels like the AM was the more challenging portion of the exam and if topics covered in the AM/PM sessions are the same at all testing locations. I'd also agree with other comments that there were some topics that were completely unpredicted. Not a lot, but a few that were not in any practice or review classes that I took.
Good Luck to everyone waiting on April Results!
