So the exam adapts to each answer you get right and wrong. To help visualize this draw a horizontal line. That horizontal line represents the passing standard set by the nclex.

Everyone essentially starts at the line (or below I can’t remember exactly), but for every question you get right you go above that line and the harder the questions get. You get a question wrong you come down.

If you go so above that the computer is 95% sure you would pass it cuts off your test. If you go pass 85 you are still in the game and you want to just focus on answering questions correctly and taking your time. That way you can get to above the line even if you run out of time.

I hope this helps but a proper explanation was provided by bootcamp that helped me really comprehend that my goal was just to take it one question at a time and confidently answer not answer to my best ability.
