Central Board Of Secondary Education [CBSE] — Every subject

I'm Ashish singh, I got my 10th marks on 3rd Of August, I score excellent in every school internal test as well as on the preboards but I got only 52% I don't know what to do now.. I am capable of getting 95% above in any test, When I told my teachers about my marks they were also surprised cause I was expected to get Highest marks in my school, They told me to appear in Compartment exams, but I just wanna ask, why is board being unfair with us, did I do something wrong? No.. Did I scored less in preboards or any Internal exams? No... Did I scored less in my 9th or even in 8th exam? No
So why is board doing this?? If you wanna take exams.. I'm ready but take it for each and every students and if you wanna give marks on past records, Implement it properly, I'm in complete state of shock since I Heard my marks.. Please CBSE do something cuz I'm unable to give compartment exams due to many reasons, The prominent one is because none will be able to cover 1 year syllabus in 1 month., it is next to impossible, when each and every one is getting good marks based on their previous marks then why not me? Why so unfair with me? You may check My past records.. Do something as soon as possible
