I just want to ask that if a student of cbse class 12th 2020 predicted the score of chemistry -70/100 biology 79/100 and in physics ge predicted 21/70 so CBSE can give him gracing by seeing others subject marks???

Rehan Alam Student Expert 5th Apr, 2020

Dear Aspirant,

No, your marks from other subjects will not have any impact on the marks in other subject. However, it is being noticed that the physics paper of 2020 was a bit on the tougher side and whenever such things happens, CBSE do lenient marking so if you are sure of 21 marks, you might as well expect passing marks.

Hope this helps. Thank you.
