Central Board Of Secondary Education [Cbse] — unfair exam of class 10 social science set 2

I am amndeep kaur from faridkot. I want to file complaint against social science exam. I got set 2 the 5 marks ques was veru difficult . How cbse imagine that student of class 10 will remember 40 regional parties. Please give relaxation. Otherwise my dream of scoring 100 will get broken in front of my eyes. It is unfair to the students who got set 2 and 3. It is not the perfect measure of intelligence. Students who got set 1 will get full marks even we prepared a lot . Why we people not deserve perfect 100. It is just the matter of luck. So cbse must give relaxation.
