I've noticed that nobody answered your inquiry. Have you done your RN refresher course finally at South Dakota State University? Were the tests difficult? It seems to me that there are a lot to study and I don't really know if I really need to focus studying on the Fundamentals of Nursing book since there are a lot of chapters to be read and I just don't know which particular matter will be given to focus for the tests. Any experience that you want to share will be highly appreciated.
