Take this posting with a grain of salt. I took form A 10 days before and Form B 5 days before. I used the standard testing mode. Form A, 440, Form B 430. Both scores foreshadow a low passing score. (Oasis says I passed, but I do not know my score yet) For me, I was more stressed about the NBME than the real deal. A score below 400 can mean bad news. A score of 500+ predicts good things. I'm glad I did it, because I felt NO stress on test day. it was nice. I wish I could say it will correlate well, but I don't know my score, (hopefully above 80#$%!) Some will say do the long version so you can look up answers. I can't respond to that. I had ONE repeat question from my NBME on the real exam, with a DIFFERENT ANSWER!!!( They asked from same column, but different value) OK confused?? I think looking up questions will be a bit of waste, but look at my score...maybe I should have..ha! 😎
