Civic Integration Exam for the Nederland. Result Makes no sense!

Hi everyone I live in the caribbean sxm. If anyone of you took the civic integration for the nederland this year maybe you can help me out here on how the test is score.
I took my exams this year 2018.

Reading skills      28 out of 30 correct (93% correct)  Passed
Listening skills     25 out of 30 correct (83% correct)  FAIL
Writing skills.          A1 level ( Fail)  A2 needed to pass

I understand that they will not let me see what i got wrong. And ill take their word for the writing part. My problem is In order to pass the listening or the reading test  you need to get 26 or higher (86%) or you fail. So even though i got 83% which like a 8 out of 10 I still fail my listening exam! I search multiple forum of users who took the nederland exam from other country or the netherland who pass by getting 72% or higher sometime even a 6 out of 10 when taking the exam.  Did the scoring method change?  Do you really need to get almost 90% of the question correct in order to pass the nederland civic exam?
