I'm in a 28 month RN program. I am just finishing up Nursing 3 (goes to N6) next week and have one year of school left (I turn 21 the week of graduation!). Nursing I had a 86%, Nursing II an 82%, and have an 83% right now in N3 before the final. I have been trying to do some sample NCLEX quizzes/questions and found myself getting in the 55-65% range on those. I took the free Kaplan 50 question NCLEX practice exam and only got a 50%. Should I be concerned?
