Central Board Of Secondary Education [CBSE] — I am complaining about physics exam

Bmit a complaint
Dear sir
The physics examination of 12th 2020 was very tough. All the questions are high order and prescribed from out of syllabus.
Students didn't get enough time to prepare also. Todays physics examination was very difficult and tricky, why cbse not understand the feeling of students? The students have not read the things which are asked in board exam anywhere neither school nor in tuition.
Then how students are able to score good in this. Only 2 or 3 questions were taught in school which have came in paper rest all are different. We want to say that if questions were this much difficult that students not even understand the questions then how can they will write something related to questions asked in this question paper
