Central Board Of Secondary Education [CBSE] — Increment in marks

I am Arush Anand, student of Vidya Sanskar School, Patna. Sir I am writing this letter because I am completely unsatisfied with the board result released by cbse on the basis of objective criteria. My expectation lies between 92%-95% of marks but the reality has shocked me because I got only 57 %of marks.
So, I kindely request the concerned authority to understand the gravity of matter and take special efforts.
Thank you
