Hey Koustab ,

According to eligibility criteria of NEET, the candidate must have passed in the subjects of Physics, Chemistry, Biology/Bio-technology and English individually and must have obtained a minimum of 50% marks taken together in Physics, Chemistry and Biology/ Bio-technology at the qualifying examination.

Qualifying Marks - UR - 50%, OBC/SC/ST - 40%, PWD - 45% (minimum aggregate marks only for PCB subjects)

It seems tough for you to get into a medical college . 

If you belong to SC or ST  OR PWD you may qualify but  not in the case of UR.
