Council For The Indian School Certificate Examinations [Cisce] — Objection regarding result of ICSE 2021

I would like to raise objection regarding results (ICSE board exam 2021) of my son Yaseen who studied in St. Paul's Academy, Patna .
He has been a regular student with a good academic record. He had always secured good marks in Geography and Biology in class 9th and 10th. He had submitted the assignments also. But he has assigned less marks in both subjects. Compared to the marks scored during school examination. I am sure that he would have scored much better marks if the board exam was conducted. Many students with less calibre secured better marks.
Surely there is a mistake/discrepancy in the computation I would send my objection through school and request you to look into this and do the necessary corrections at the earliest.
Thanking you
