Hii

The cutoffs vary every year so it is very difficult to say what marks would be required for admission. But as per the previous year trends, 580 marks in OBC category are decent enough to secure a seat in Banglore Medical college
In 2018, the cutoff range in OBC category was 469 - 466 for this college.
Rest we need to wait till the exam is conducted and cutoff is released. There are many factors that determine the cutoffs. So official information is necessary before any predictions are made.

Hope this helps
Thanks!!
