Central Board Of Secondary Education [CBSE] — difficulty of set 1 maths question paper

Respected authority
I would like to draw your kind attention towards the difficulty of set 1 mathematics question paper of class 10, which was held on 7-3-2019. It was very difficult compared to set2 and set3 question papers.
Set 1 contained somany hot questions especially from chapters triangles and trignometry. 4 mark questions were very difficult.
We appeal to the board to do linient marking and do justice towards the children so that their effort and hardwork which they put on for this exam will not go in vain
