Hey dear, cutoff varies every year, seeing tpur marks i can say that your rank will fall between 83000 to 100000 for sure. If you see the last year's cutoff which went very high that even students getting 500 marks were unable to get a govt. Mbbs college. So with 457 marks you chances for govt. Mbbs are less, but you may go for bams and bhms. You can also use college predictor through this link:
