Central Board Of Secondary Education [CBSE] — request for lenient evaluation of mathematics exam of class 10

Respected sirmam
I'm a teacher i would like to inform that mathematics paper was very hard especially set 1. I got the same feedback from most of the students so i'm requsting cbse that please give grace mark and liberal marking pls
From ancient times in india, examinations are termed as sacred and i believe cbse as a holy organisation spreading education but now i'm really disappointed in cbse due to this chaos. As a teacher it feels awkward to see different questions in examinations especially boards.
I hope my request (Not complaint) will be heard because in india, we are taught to raise voices against any unfair practices.
