Central Board Of Secondary Education [CBSE] — Not satisfied with result

Address: Kota Rajasthan

Currently I am the student of class eleventh.I pass out my tenth from Shiv Jyoti convent school, Kota Rajasthan in session[protected] . Actually I have a problem with my result, as everyone knows in this session board divides tenth board into two terms in term -1 I got 180/200 but in term -2 I achieved only 150/200 so couldn't believe.
Now I applied for verification of marks but there is no change in marks now again I want to re-evaluate my marks but it is very costly and I belongs to a farmer family so I can't afford and want smy checking at free of cost.
I have completed by classes before the tenth from RBSE school but my father believes I am a brilliant student so he decided to admit me in Cbse board school.
Please do the honour for me
