Central Board Of Secondary Education [CBSE] — I'm complaining about hindi board examination of class x held on 19/03/19

Address:

RBN Global School Anaura Kalan, Faizabad Road, Lucknow, Lucknow, Uttar Pradesh

Through this letter i arvind kumar chauhan wants to submit the problem which was faced by my ward shiva chauhan including other students of his class on the 19/03/2019 during hindi board examination.
The problem is that in rbn global school hindi course-a was taught to the students of class x throughout the year. But in the admit card hindi course-b was mentioned. No one of school management concentrated on that. On the 19/03/2019 when students of rbn global school got there hindi paper they were all surprised to see the paper because it was the paper of course-b. At that time they have no any other chance except to write the paper. It was not the fault of the students. Many students got depressed due to this. The mistake done by management have to bear by the students. So, please try to solve this problem as soon as possible. Can you conduct the paper of hindi course-a of class x of rbn global school. If not then what action should be taken & what about the hard work of students during the year.
