Mumbai University — inappropriate exam results

This complaint is regarding the inappropriate exams results of 6th semester tybms april 2017. As per tybms results of 6th semester, my marks are displayed to be 6 (Single digit number) in subject operation research (External). As per me it has to be thoroughly evaluated because of the following reasons - i have never attempted any re-exams till 5th semester and this wasn't expected. I scored the following sgpa in the following semesters
I - 5.57
Ii - 5.86
Iii - 6.83
Iv - 6.33
V - 6.00
Vi - 418 (Total marks)
Moreover i have scored internal marks 18/25 in operation research.
What so ever the reasons, at least passing marks were expected according to the previous records. Kindly revert at the earliest.
