Central Board Of Secondary Education [CBSE] — Unfair marking is being done by U.S.Academy and Institute, Gorakhpur

My school has given unreasonable marks to the students. Like my name is Kunal Mani and I got 90.8% in 10th Boards and 81% in class 11th (Highest in PCM at Bargadwa branch) and in-class 12th school wasn't able to complete even half of the syllabus anyhow they were able to take midterms exams and I was in top 5 in that exam also but at last when I saw my 12th boards marks(82%) I was in shock because those students who were far behind than me have topped the list. Many top listers who were failed miserably in class 11th and 12th have gotten 90+% marks(Note:-There class 10th percentage are also lower than mine).This is not only the case of mine but many students of my class have suffered from the same. FAIR MARKING SCHEME HASN'T BEEN ADOPTED BY THE SCHOOL. This is demoralizing and disrespectful to the efforts and hard works of all the deserving students. What marks the school has provided us in the Boards is not MATHEMATICALLY correct when CBSE marking scheme criterion is used. Please look toward this matter and if possible CBSE calculate our marks on our school behalf.
