Central Board Of Secondary Education [CBSE] — I am complaining about my result which is not ignorable

Address:

Thanjavur, Tamil nadu

I had got more than 60 marks in all subjects on 10th standard and in 11th my marks are good as compared to my 10th and my final exam In 11th is also above 380 and in my 12th standard I took more than 50 out of 80
But in my final result my maths marks are consider as too poor. Please consider my complaint and take action about this and please don't ignore this... Thank you.
