Hello aspirant
Hope you are doing well
It is difficult to predict the cut off marks or ranks but according to previous year trends your expected rank would lie between
With score 550 - 56076 - 68226
With score 560 - 48335 - 58485
but it may vary every year depending on the following factors
1. Level of question paper
2. Total no of candidates
3. Category of candidate
4. Total no of seats
5. Marks obtained by students
Here is the link for the rank predictor

So considerung you as a general category candidate the cut off in 2019 for St John was around 528 marks
So you have chances to get seat .
