Can you please specify in which state you have state quota as then it would be easy to predict colleges. However in general you need to have more than 460-480 marks to get a MBBS seat in government college under state quota. The cutoffs differs from state to state.

I would suggest you to refer to the neet college predictor tool in order to know about the options you have.
