Central Board Of Secondary Education [CBSE] — Science/math/social science/hindi/english

Requested sir/mam,
I am Pallavi priya, daughter of Mr Manoj Kumar Ranjan, Student of Anand public school sabour, bhagalpur . My roll number is 22132551 . According to the CBSE criteria our teachers should give marks on the basis of last year performance, were I obtained 93 percent marks . After complaining in school they are saying we are sorry for your low marks we made mistakes in giving marks . Sir this is not a minor mistake it can harm our future . School authorities are saying u should appear in improvement exam/re-exam and sir their is not enough time to revise all syallabus in this short interval time .
Sir, I kindly request you to take some action on it and verify our results again so that we can get our deserved numbers . Thank-you sir ..
