I called ADA myself and spoke to a NBDE coordinator to find out what is going on with the scoring on the new format. So here are the points they told me:
#1. The scoring of the exam is based on a SCALE and not a CURVE. Therefore, your score does not depend on how other students do. The scale for this exam was determined by the test makers, based on pilot exams and previous board exams. So essentially we are using a scale based on the curve of previous exams. That explains why people are scoring lower.
#2. Each question is worth a different amount of points. Questions that are considered "harder" are worth more points than "easier" questions. That is how two raw scores of 83 can each amount to a 92 overall or a 89 over all.
#3. The coordinator assured me that a score of 90 on the new exam is equivalent to a 90 in the old exam.
#4. A score of 90 is considered to be around the top 20%.
#5. Scores from each different exam format can be compared to each other because each format has an equal number of easy, medium, and hard questions.
#6. There will be a recalibration of the scale in september/october of this year.
