Central Board Of Secondary Education [CBSE] — Got unexpected very less marks in 12 th board exam 2021

Address:

Mumbai

I want to draw ur attention towardsmy result. I got only 76 percent in 12th board .I am an aspiring student for IIT JEE and BITS exam for which PCM Mark's criteria is 75 and I just got 74 percent in PCM so even not eligible to exam .
I am a bright student throughout my academics. Got 95 percent in 10 th ICSE board and 92 percent in 11 th . Completed all my assignments, projects, practical and Preboards of my school.So this much less result was not at all expected.atleast 92 and above percentage I was expecting.
Appearing for re exam is not at all possible interrupting my JEE and other exams preparations
On the top of it we have shifted from Kota to Mumbai and took my all exam centres from here .So again appearing for board exam from Rajasthan in my entrance exam schedule is not at all possible
So pls look in to the matter and resolve this issue earliest as this result has hampered my and my parents mindset
