Mysel[censored]jjwal Gupta, resident of Agra .Till class 10, I was enrolled with ICSE board and in class 10 I secured 97.6%. In class 11 I changed my board and was enrolled with Dr. Maria Residential Academy Agra. I did my class 11 from here only and secured 92.1% but in class 12 school has awarded me with just 73.4% which is very unfair and school is also not providing me with pre-board marksheet.My board roll no. is 21610726. My school code is 60039.I request the concerned authorities to look into into this matter as soon as possible.
