Central Board Of Secondary Education [CBSE] — Our school gave unfair marks and discriminating with students

Respected sir/mam,
I am a student of class 10th from patna st. Michael's school ashok nagar kankarbagh patna, bihar

Sir/mam, As we all know that due to this pandemic class 10th cbse board examination were cancelled and yesterday on 3rd August our cbse class 10th result has been declared on the basis of evaluation criteria but my school gave the result on the basis of relation and favoritism with students and some students who actually at the level of failed in pre board examination but they got 80-94% on cbse board examination. Most of deserving students having unfair marks also including me I scored 86% in pre board but I got 68% in cbse board examination.
And I also contact with my school administration they said the result has been given by cbse and say I don't know anything about it.
So, please I request you to recheck the marks has given by our school teacher and school administration and ensure that marks give only deserving and hardworking students.
