Hello student,

It's difficult to predict about the exact admission possibilities. Cut-off differs every year on the basis of several factors,such as the number of students appeared, the number of students qualified, the difficulty of exam level, whether you belong to any category or not. As cutoff changes based on different categories. It varies from state to state. It also differs from state quota seats to all india quota seats. Karnataka has 15% all india quota seats and 85% state quota seats.

As per previous year's cutoff, chances seems less to get a mbbs seat in Karnataka with 300 marks in NEET exam. This data is based on the last year's cutoff.

You can have admission chances in deemed universities and private Colleges. Use NEET college predictor tool to see which college you might get based on your rank/score.
