Yes, I have taken the exams-- in fact, several years ago after having been out of school for almost 30 years!!!!!! Everything that folks are telling you is accurate-- take it NOW! There is nothing spooky about this-- the "hoop" portion is probably the most frustrating, however, we have all jumped through the hoops!
You have a great plan-- BSIE/MSEM/MSIE-- USF is a great place-- I knew a professor there-- Dr. Lucy ?????? Forgot Lucy's last name. She is involved in American Society of Engineering Management---- as am I.
OK, let's review again-- go to NCEES.org and review what they say about the FE. Go to Engineerintrainingexam.com and review what he says and does. Get Lindberg's book, 1000 FE problems and work all of them, over, over, over, over, over and over again until you can do it without thinking about it.
It appears that the CBT portion of the FE will be somewhat different than the paper based exam. In that, I mean, reviewing from the NCEES web site, that the elements of evaluation will change somewhat. At this point, I don't think that is important- get Lindberg's book and study. With your GPA-- you should not have any trouble blowing this out of the water on the first attempt.
Your school may have an FE prep course-- I would take it-- there are some other prep courses here on the web as well. Do not know anything about them-- cannot make any suggestions/recommendations because I never have used them. The reason I do suggest Engineerintrainingexam.com is that the guy makes it fun, is interesting and it is free.
I don't know what it costs to take the test-- the NCEES web site will tell you that, along with your state web site-- plan on spending $500-700 for the FE. That is for all the license fees, registration, etc. If you have to go stay in a hotel at the testing site and have to eat out for a couple of days, add another $300 to that. If you have a friend close, then, buy the friend dinner and subtract $200!!
BOTTOM LINE-- Get the books and get started. This is not spooky. Congratulations on receiving your BSIE degree! You will do well with it. USF is a great school and they have some great IE faculty there. I remain impressed that you have a plan and are executing the plan.
NOW, I will say if you are going to go straight through from BSIE to MSEM to MSIE-- your starting salary will PROBABLY NOT be significantly and substantially different than a beginning IE with a BS degree. Why? No actual job experience. This background, coupled with the FE/PE license will make you golden for a consulting gig--. Money is great-- however your butt is on an airplane every week. Works well with you are single, however, if you find a wife/husband, then, this sometimes does not work ouit near as well.
I have a friend on the faculty at Texas Christian University at the Neely School of Business. He told me yesterday that his top undergrads are getting great jobs in Supply Chain Management-- IE type work. Some of the kids were getting just at $80K/year working for a big consulting agency. Again, consulting money is very, very good. Living in a hotel, eating out and flying is a big deal for about 3 weeks, then it becomes a real drag. If you can gut it out and do it for 10-15 years, you rise up and do very, very well financially. However, most folks are unwilling to make those sacrifices.
