Central Board Of Secondary Education [CBSE] — I'm complaining about my 10th class marks.

Address:

CBSE (head office) Shiksha Kendra , 2 , community centre preet vihar, Delhi -110093

I got very less marks than my academic record and not satisfied with my 10th marks.(53.8%) There has been discrimination in the school, the student who are good in studies got very less marks but the student who does not come to school they get more marks than me and their academic record is also not good.
The school's result committee gave better marks to those students who were in their favor.
