Central Board Of Secondary Education [CBSE] — Not satisfied with Class 12th board result

I am Prerak Lodha from Jayshree Periwal High School, Jaipur. My board roll no. is: 11666814 and I am highly disgusted with the assessment of class 12th board percentage by CBSE. I secured 92% in class 10th board; had a downfall in 11th with 64% but in class 12th pre board - I (results of which, were declared and then removed by the school from the cloud storage), I scored 85%. But in pre board - IV, I scored a minimum of 90% in Chemistry (could be higher, not sure as the school did not declare marks) and in IP, my strongest subject in which I used to score above 93%(once, but generally above 95%) I was given 90% despite scoring 98% (could be a 100) in the pre board - IV, on what basis?? And if we consider aggregate of all the 3 (also considering that school takes the marks of the best pre board) I should have got a minimum of 85% but I was dropped down to 78% !!

Other than me the less deserving people (includes some of my friends whom I know well personally) who should have scored around 60%, people who barely pass by scoring 30-40% and also the more deserving people who should have got above 95% are getting percentage in the range of 80-90.

Schools have also shown unnecessary and excessive partiality to the folks who are persuing international education just to improve their status and maintain the average, which has in turn resulted in decrease in marks for the above average students

I have been selected in SRM University, Chennai with a scholarship of 100% and do you expect any child to ruin their 12th board results just on the basis of their 10th and 11th standard results? If it was not for COVID-19 it would have been easy for me to score above 90% in 12th board. But for our partial teachers and the so called highly educated principals the matter of declaring results is just like a number game. They have to plan according to CBSE guidelines but may crush a child's percentage just to maintain their average.

I request a raise in my marks and proper action from CBSE against these types of schools.
