Rajiv Gandhi Proudyogiki Vishwavidyalaya [RGPV] — For getting failed in exam...

Hello sir/ mam,
I'm student of MCA (2 year). yesterday my first sem exam result declared and very shockingly and unexpectedly I got only 12 marks in statistical mathematics...which is not at all bearable by me ..
As I'm the bright student, also I did well in exam then how it is possible that I got only 12 marks...in our question paper 1 st question is of 14 Mark's and it is completely right as I checked my answers with the book...so how it is possible that I got only 12 marks...I have attempted all questions and which is almost correct then how I get only 12 marks..
My classmates who did not write anything in paper and leave blanked answer sheet they all got passed in mathematics...
Please don't play with tha future of studious students...I have already filled the revaluation and retotaling form but I'm very nervous that I did not get Mark's again... please consider my problems...
