Exams vary from one test to the other. if it were less than 35%, it may have been done intentionally to prevent confusion.
With implementation of the new TRID disclosures, and changes to TIL & RESPA, the governing body may have wanted to eliminate those areas for possible confusion over what applies.
Only a guess - they did not ask for my opinion on test questions this time..................
