My son appeared for the 10th standard exam from CBSE Allahabad region and secured full marks in all three subjects maths, science and social science, English 95 but he got only 83 in Hindi. He is very confident that he should get more than 95 in Hindi. Please advise if I can file a writ petetion for the revaluation of his Hindi paper. Also please advise under what section this writ has to be filed and where. We firmly believe there is a serious mistake in the valuation. Kindly advise.
