Central Board Of Secondary Education [CBSE] — leaked mathematics paper

Sir i think cbse paper is a joke.
Cbse is conducting the mathematics paper again for all students.
The paper was only leaked in delhi region then also cbse board is conducting the paper for all students.
This is not fair.
Cbse is not concern about paper.
They just think and consider it is a joke.
Cbse board is so careless, why should all students suffer because of them.
If they are careless then why should all students pay because of this.
Atleast, if paper has leaked in delhi then why should the students of rajasthan suffer.
