Central Board Of Secondary Education [CBSE] — I'm complaining about how my school has given wrong marks to cbse for boards 2021 and blamed it on cbse's new moderation policy

I'm Ira Sharma a student of Central Academy School, Ajmer. My top 3 subjects percentage in 10th grade was 91 and overall 87 percent. I scored 90℅ in 11th grade and 96℅ in my 12th boards practical. And the cumulative score I've received in boards 2021 cbse is 76.6 ℅ This percentage can ruin my entire carrier and I definitely do not deserve this. I talked to the central academy School ajmer's vice principal and he said that your percentage has been dropped from 90 to 70 by cbse's new moderation policy. If moderation of only +/-5 marks was allowed how did I score 76.6 ℅ from 90+. I want justice.
