Central Board Of Secondary Education [CBSE] — examination

Respected sir,
Science examination was conducted on 13th march 2019 for grade 10. The students who wrote set 2 was unlucky as they got higher order thinking questions when compared to set 1 and set 3 as the questions were directly from textbook for them. The students who wrote set 1 and set 3 can easily score good marks. Just think about the students who wrote set 2 which is very difficult. Please do show some justice to them as everyone should get equal preferences. There is no value for hardwork taken by students only about luck being a factor. Please take necessary action against this and even mathematics exam of grade 10, set 1 was difficult and think about their situation. One way to solve itby making correction liberal for the difficult papers.. Please take the actions.
