Central Board Of Secondary Education [CBSE] — School giving unfair marks to students

Address:

Devru Road Sonipat

Yesterday our board result was declared and my school give me only 70% because I study through 134A act.
134A is act launched by haryana government so that poor students can also study through private schools without giving any fees.My roll no.is 17250983 and my school code is 41111.All other students who study via fees are given higher marks then me even most of them were fail in half yearly exams.My friend who was the topper of Class 10th half yearly exam had gain only 75% because he also study via 134A act. I request you to please look into my problem and take immediate steps.
