Central Board Of Secondary Education [CBSE] — tough physics paper with less time duration

The physics paper of 2018 can be considered 1 of the toughest papers. Many students have not been able to answer the paper even after preparing a lot. Most of the students have found it tough.
Urban schools have good teachers nd facilities. Sub urban or rural prople donot get such quality education to answer such application and numerical based questions.
No theory no derivations no sufficient revision time highly difficult for average students to even score the minimum passing marks. Previous year papers were quiet lot easier than this years.
Please look into this and take necessary action.
Either a re exam or grace marks

Sincere request... Dont spoil the future of students... Think about people who donot get proper facilities still trying to study... Their hopes r shatered... Please do justice to all
