Central Board Of Secondary Education [CBSE] — Regarding marks allotted in theory of painting

Sir I am Vaibhav Raj a class 12th student. There has been some mistake in allotting my marks in theory of painting. I have been given zero in the theory paper of painting which is not possible. I have even contacted the school regarding this matter and they have clarified that they have given sufficient marks in this subject. I have even sent mail to the concerned authorities of CBSE. This situation has stressed me a lot so, sir kindly look into this matter and make the necessary corrections.
