Hello, 

As you have mentioned that your neet score is 511 marks which indeed is good score.. But you haven't mentioned your category. Nevertheless, if you fall under general category then your chances to get MBBS seat are very less.. But if you fall under the reserved category then you have good chances to get MBBS seat under 85% state quota seats.. But if we look over previous year's cutoff for MBBS then, you too have chances to get a seat under 15% All India Quota..
