Respected sir,
My self krishna kumar, student of vj international school Bhagalpur my school code is: 65540
And my roll number is : 22134840
Sir, I got in 279 marks out of 500, in each practical exam I got 20 out of 20 and in written exam I got 30, 35, 44, 40, how it can be possible without taking my exam how my school can decide that I will get 30 marks out of 80. So it looks like unfair practice happen with me, so I request you sir please check my marks and do needful, I always got 90%marks in my through out carrier now how I can belive that I got only 55.8% in my class 10th exam, which I did prepration for day and night...
My school were asked me for brief for good result, so my guardian denied thats why I got this much less marks,
Those who got marks all they pay handsome money to my school that's why they got good marks, you can send a team and can take interview and can understand the truth...
Please do needful for my result...
