Looks a lot difficult brother especially if you are from general category. And this year toh you might also be knowing that the cutoff is expected to rise since the number of candidates had increased and also the paper level was called easy comparatively. So around 470/480+ would have been a safe score. Best wishes to you. 

Hello aspirant,

The cutoff of St. John Medical College is higher than your score for general category candidates. So the chances are less of getting a seat. The cutoff remains low for the candidates with reservation. So you can opt for some other colleges. You can get MBBS in private colleges.
