I am taking CGFNS exam on 13th of July. I knew about it only few days ago when one of the CGFNS person called me and confirmed the exam schedule. I finished reviewing the CGFNS official study guide and Kaplan book. Now, I am doing some CD practice tests..my score is around 65-75%. I am worried about the exam,,how much practice score is predictive of passing the actual exam???CGFNS is a paper pencil test,,but quite similar to NCLEX,,how helpful are the NCLEX preparation books for CGFNS? please give me some tips.
