Hii there, to get admission in St. John's Medical College, you must do KEA counselling afte qualifying NEET and PGET respectively. In 2019, the cutoff for MBBS closing rank was 34157. In 2018, the closing rank was 65297. So it differs from year to year, maje sure you apply to the counselling and follow all the procedures accordingly. Hope it helps.
