Hello Rohit,
As per your query about marks cutoff, you must be knowing that there is All India Quota 15 % and State government quota 85%...

Cut off by All India quota is always higher than state quota..
Further in both the quota the SEAT is further divided as per category like Open, SC , OBC , ST, etc..It will vary for each group.
The Cutoff also vary in Government, Private and Deemed University.
Also difffer college to college even in government /private/deemed.
The marks vary each year based on the difficulty level of the paper

BUT GOING BY PREVIOUS YEAR TREND A MBBS SEAT is obtained around 480 - 600 marks range..


Hope it helps
