Central Board Of Secondary Education [CBSE] — Marks in grade[protected]

According to the criteria given by cbse for the marks of 2020-21 batch students are to be given according to the school's result in last 3 years . All the students in this batch in Siddhartha public school, kanjhawala road, new delhi, have got disastrous results . I scored 94.4% jn class 10( icse ) and 93 % in class 11, i have got 82% marks in class 12 cbse . I look forward to someone from the central authority to explain the criteria on the basis of which we have been given such results . Our admissions and career has been threatened with such marks .so, please look into the matter.
Thankyou.
