Central Board Of Secondary Education [CBSE] — CBSE grade 10th results

Address:

Habitat School, UAQ

Respected sir/ma'am,
I'm a student from habitat school uaq, submitting a complaint against the unfair evaluting system of class 10th results.
Reference, register no. 27121465
According to all exams from my grade 1st to grade 9th, i've never scored below 90% in my academics but once i got my cbse grade 10th result it was not the case. From the conducted precious exam in my grade 10th, my percentage was never below 90 as well and i got around 93% for both my mid term exam and pre board exam for my class 10th. But in my cbse board annual result, i got only around 83%. Basically socail studies was my personal best subject and i have never failed to get a mark less than 95 in sst, but in the result provided by cbse i just got a 73 which makes me wonder how my 95+ marks have decreased to 73. This happened the same with my science marks. I have always scored above 90 for science but i got a 77 for the cbse result. This is not acceptable and so unfair in a student's life and this makes a student feel so demotivated.
I think either my school provided the cbse w wrong marks of mine and played w my marks or there is some error from the side of CBSE .So i humbily request to look into this matter as soon as possible and give a fair and acceptable response. please do be fair w this matter.

All the exam results fof my PA2 and PRE BOARD exam have been attached down below.

Thank you,
Aiswarya.
