Central Board Of Secondary Education [CBSE] — difficulty in physics paper for chennai region 2018

This time physics paper for chennai region was too tough and too lenthy. We lost our almost 2 hours in section c itself and could not able to complete the paper. Section c was full of applicative level and seems to be meant for only intelligent students. Giving one day gap and expecting us to write such a difficult paper is injustice. Give us atleast 20 grace marks.
