Hi All,
I just wanted to share my experience with the board exam in hopes that it will help you.
I took the exam in April of 2012....and...I passed!
I finished the NC program in Dec 2011. I studied on my own, at least 2 times a week from Feb - April (and btw, was 8 month pregnant during the test, so you can have other things going on in your life & still make it work

I created a weekly study schedule based on the NANP study guide booklet - that helped to keep me on track & made sure I covered
most topics.
Going into the test I can't say I was overly confident...more so I was just neutral. I really had no idea if I was prepared enough for the test - the NANP study guide is so broad that it was hard to know if my studies & Bauman skills were going to be enough. And in truth, I found the exam to be quite challenging. Despite having done quite well with my Bauman studies, I walked away from the board exam truly questioning if I had passed.
For my studies I reviewed all Bauman quizes (FON & TN/NC).
I mostly used the Bauman powerpoint slides to review the information that came up in the quizzes, occasionally used the Bauman handbooks, and frequently used the Elson Haas book recommended by the NANP, "Staying Healthy with Nutrition" (I loved this book...and wish had been part of the Bauman curriculum).
And of course I used the NANP study guide. The study guide itself was a little disappointing...I felt like I had to pay $$$ to get NOT a lot of info or guidance about the test (there were only 25?? sample questions & a huge list of topics to study). That said, I probably could've paid more attention to the study guide and focused more time on the Nutrition in Practice topics - yes they are huge topics.... but on the test I found questions regarding, for example, rosacea... I don't recall having studied that at Bauman, but it was definitely on my exam. Other conditions that I hadn't recalled studying at Bauman were also on the exam...but they WERE listed in the study guide... so I guess it's best to follow that study guide, daunting as it may seem. I don't think you have to know deep details about each condition in the study guide... but more so a general overview.
The test was a mixed bag...some of the questions I felt like I would've known without my Bauman training, some I definitely needed the Bauman training, and some I just didn't know at all (I'm not sure if I missed those topics @ Bauman...or if they were just topics included in the NANP recommended reading... which I definitely didn't complete.... they recommend a lot of books!)
The good news is that the combination of what I did know beforehand, learned at Bauman, and learned in my studying for the board exam, all added up to be enough!! Even in light of the questions that I just didn't know the answers to, what I did know was enough!
Challenging for me, yes... but I'm proof that you can do it!
I actually enjoyed the structured studying & it helped me to review all the good stuff covered at Bauman. It was good to have the motivation to review & pull it all together.
I'd say do your best to study the topics in the NANP guide, and review Bauman materials.... you're probably not going to know it all, but from my experience, you'll know enough. Good Luck - you can do it!
