According to me..the pattern of question Paper that cbse designed for class 12th boards is totally different from sample papers shown by cbse .

• Which contain some new questions which make difficulty for students and even most them are numericals based .
• Paper was too lengthy as well which made difficult to complete paper  within 3 hours.

For that Cbse have to do lenient marking for betterment of children as their future colleges are opted by them on the bases of their overall percentages.

Hope that cbse do better for students.

According to me, 2019 CBSE Physics Question paper was moderately easy. However it was a lengthy paper, perhaps, due to which many candidates failed to complete the paper in time. Grace marks should be awarded to all candidates in my opinion and CBSE is mostly likely to award grace marks to all candidates.
