I am currently studying for the CNOR and am trying to get a feel for if I am prepared or not. I know the score to pass is at least a 620. Does any one know how that would translate into a percentage? I am taking practice exams and scoring anywhere from an 80-85%. Are these sufficient enough scores to translate into a 620 on the day of the exam? I have about 40 days until my test date. Any info would be greatly appreciated.
