Dear sir,
I get good marks in unit test, half yearly, pre board 1 and pre board 2 in class 10. But when the 10 th board result came to light there is a huge differences between board marks and my class 10th school marks. By your board marks tabulation (10% in unit test, 30% in half yearly and 40% in preboard) i am scoring 81.6%. But in real i get only 51.6% in cbse class10 board exam. I am preparing for class 11 now. Class 10 has 5 subjects and also class 11 has 6 subjects (including additional). It is impossible to prepare with this 11 subjects for taking 10th board exam again. If there is a review system or any solution for dispute resolution without any court case please sir inform to me. Hope you understand my distresses.

Thank you
