Hi, I'm sorry to hear you didn't pass the exam.
PMI don't publish the exam pass mark, so there is no way to know what the scoring mark is.
You know the exam is different - I think the best way to understand the differences is to read the new Exam Content Outline. I found that helpful. The PM PrepCast training and the PM Exam Simulator are both updated to the latest version of the exam so those are the materials most of our students are using.
