Probability of passing is messed up – My Mastery: NCLEX & Nursing Review

This app is ok, I like the rationales. Some questions are a little ridiculous but whatever. However, how is it going to tell me I had a 46% chance of passing the nclex, and then the next update tell me I have a 9% chance. How is that even possible
