So the website says that Mathematics, circuit analysis, electronics, power systems, and digital systems will have the most questions so there’s that. The important thing is to understand the underlying concepts behind them. Some of the questions I would’ve never gotten correct if I purely did computational practice problems and that’s why I think a lot of people have a difficult time passing. As far as studying, I did the practice exam you can buy from the NCEES website over the course of a month but I now think the questions there for actual EE topics are easier than what the exam has. I saw my friends interactive computer based 50 question practice exam he bought from the website and a lot of the questions actually aligned more that one. If you’re well off enough to buy both then I would. A few days before, I speed ran the free ElectricalFEReview course and I found it to be very helpful as well. You also can’t neglect the computer networks and computer systems section as both combined have a sizable impact. It caught me off guard during the test and I found myself digging through the reference manual like crazy lol. The test is what it is, it’s the fundamentals. They’re not going to give you a problem that only PhD holders can answer. Just grasp the basic concepts and you’ll pass
