Thanks! Think three key factors contributed to my success: work experience (both my past experience in IT and current experience in NI), ANCC Informatics Nursing Study group, and having taken a Nursing Informatics course over the summer.
Overall, the exam was moderately difficult. Meaning for questions pertaining to just Information Technology thought they were easy because I have a strong IT background, but for questions relating to NI, the level of difficulty range from moderate to challenging.
Having completed the Informatics study group (highly recommend), there were no surprises because it prepared me well for the exam. Therefore, that helped to create the perception of "didn't surprise" me.
