you can get seat even if you are qualified in  NEET for management quota

Hey Swarna,

YOU have to give NEET and apply for college by form filling, Counseling was done by Karnataka Examination Authorities KEA.. 

I would also like to inform you that it will vary each year, depending on the difficulty level of ques paper, number of students scoring that mark.. Also it will vary you applying through ALL INDIA QUOTA, TOTAL 15 seats are for open for all irrespective of religion, other 135 seats are reserved for Christians only...

According to previous year cut-off marks St John's Medical College demands for atleast 450 marks.

Your mark is 487 so there are high chance that you might get a seat in the college.

Hope this helps,

GOOD LUCK!
