I just completed my NI exam and passed!!!!!!Woohooo!!! For those who are planning on taking the exam, I highly recommend taking the Informatics Nursing Study Group by Marisa L. Wilson DNSc, MHSc, RN-BC. It's an 8 week course, but definitely worth the time. In addition, I recommend purchasing the 150 sample exam that ANCC provides. I learned a lot from it and gave me the opportunity to practice on my test taking skills. Good Luck!!
