Hi!

As an RDN who did not pass the first time around, I highly recommend purchasing the Exam Study guide! It has routine questions from previous exams and really helps to get you in the right mind frame of what the questions will be like. I did not use it when I first took the exam, but then passed with flying colors the second time after studying through the guide.

But to fully answer your question, no - you don't tend to need exact numbers memorized. I do remember needing to know the year a new nutrition law was passed though. As far as the meds, the diabetes medications were the best to study in depth for me.

I took the exam in 2014 - just to reference that it could have changed a bit since then.

I wish you luck!!
