Central Board Of Secondary Education [CBSE] — Regarding dissatisfaction about 10th results

I am vijaya laxmi. I scored 94% in half yearly, above 80 percent in all periodic tests and 80 percent in pre boards conducted by the school but they gave me only 39 marks in science when i have scored much more than that in all science exams... They did the same with sst and Sanskrit also... My school code is 65402.i demand to see all my previous results and what my school sent to CBSE. I demand for inspection.
