I'm an EE, and I just took the FE exam in October for the first time. Despite being out of school for over five years and not being familiar with most of the subjects on the exam (thermo, fluids, statics, dynamics, materials, etc.), I somehow managed to pass.
I took a review course at the local university, and it was pretty useful. They used the FE Review Manual from PPI (author is Lindeburg), and they had used copies of the official FE reference manual that you get at the exam.
Here's my advice:
1. Register for the exam immediately if you haven't already. Deadlines are generally a couple of months before the exam, and don't expect them to make any exceptions. My state board says if you don't have your application in on time, you have to wait for the next exam, NO EXCEPTIONS.
2. Get a copy of the official FE reference and get very familiar with it. It's the only book you will be able to consult during the exam. There is a lot of stuff in the book, much of which you won't need on the exam, but there are plenty of problems that can be easily solved if you just know where to find some information or a formula in the book. Don't expect the book to have everything you need, though. Due to the number of questions you have to answer vs. how much time you have to do them, you won't have a lot of time to hunt around in the reference book.
3. Buy Lindeburg's book and work through all the problems. I found the actual exam questions to be either just like the Lindeburg book or a little easier.
4. Make sure the calculator you currently own is on the approved list. It's a small list, and they are very strict about it. You don't want to be fumbling with an unfamiliar calculator on exam day.
5. Unless you are fairly up to speed on electrical subjects, you probably should plan on taking the general exam in the afternoon rather than the discipline-specific electrical one. As an EE, you're probably going to have a learn a lot of new material for the morning exam, and it will be the same subjects in the afternoon (albeit with more difficult questions). You probably don't have time to study all the new material for the morning and study for the discipline-specific electrical afternoon exam. You should probably call your state board to make sure it's OK for you to take the general exam. I've heard some states require people to take discipline-specific exams if they are available. You will get to look over the afternoon exams and decide which one to take during the exam. I thought the electrical exam looked pretty hard, so I took the general exam, and my state board is OK with that.
6. Pretty much everyone used the entire four hours during the morning exam, but a lot of people finished early during the afternoon exam. I used all the time allotted. True, they don't allow scratch paper, but there's enough room in the exam book to work the problems.
Overall, I can say that objectively the questions on the exam weren't all that difficult. I found a lot of the questions difficult because I was unfamiliar with the subject matter. On the subjects I did know, I found the problems to be almost laughably easy. What makes the overall exam difficult is that you have to know about a lot of different subjects. So the key is to get familiar with those subjects ahead of time.
