Hello Aspirant.

Hope you are doing well.

There are less chances of you to get the admission in the government medical college karnataka with 27000 rank . But the cut off varies every year so maybe you'll get the admission because cut off depends upon various numbers of factors such as the difficulty level of exams, no of candidates, etc. But the cut off for the reserved category is comparatively low than the cut off of unreserved category.

GOOD LUCK, STAY MOTIVATED AND HOPE THIS HELPS.

Thankyou.
