Central Board Of Secondary Education [CBSE] — complain about hindi paper and science paper

This is with reference to the hindi exam conducted on 29/2/2020 for 10th grade. Question no. 6 of set-3 of muhavare was out of the syllabus and very tough.
This is with reference to the science exam conducted on 4/3/2020 for 10th grade. Question no.23-c of set-1 was also out of the syllabus.
It's not fair for the children if one set is easier than the other.
Kindly look into the matter and do the needful.
