Low Risk Newborn RNC exam

Hello there!
I didn't know where to post this, but this forum seemed the most appropriate.
I work in a level 1 (and 3/4's, as we like to say) nursery and am preparing to take the RNC exam for Low-Risk Newborn. There are no real study guides out there for this exam, like for the NICU RNC. I have several NICU books (i.e. Merenstein & Gardner's "Handbook for Neonatal Intensive Care" and Cloherty's "Manual of Neonatal Care") and have been reading them.
Has anyone taken this exam? If you did, how and what did you study? Most people I know have taken the NICU exam, and I have yet to find someone who has taken the Low Risk.

Any advice would be appreciated greatly!
