How long had passes before you go to 75? I think the first break is around 2.5 hrs or so

I don't believe that is correct. Regardless, the computer will "hiccup" or sit for a few after question 75 as it calculates possible pass or fail. It's not going to pause and continue if you're not doing well, it will stop. The only reason the test continues is if you ARE doing OK. It only stops when it knows you either A) cannot pass or B) have answered enough correct high level questions to pass. (unless you hit max # questions)

Sounds silly, I know.

After testing for the first 2 hours, the computer will ask if you want to take a break...doesn't matter what question number you're on. For those who are "fast test-takers," question 75 is reached before the 2 hour mark. And if the candidate has not demonstrated minimum competency, then the computer keeps going.

Set Your Pace

You'll have up to 6 hours to complete the RN exam, 5 hours for the PN exam, including the short tutorial and 2 optional breaks (the first 2 hours into testing, the second after 3.5 hours of testing). Take time to analyze each question carefully—once you submit an answer you can't return to that question. Learn more about computer adaptive testing (CAT).
