Dude admission depend on your score, your state and your category as well
But score of 275 is low for candidate to get admission in govt college.
You may have chances of private college

275 marks are less to get a govt . Medical seat. But you may have chances to get a private seat or you can get a seat through management quota. Or otherwise you have an option of Drop.
All the best for future

275 score is unfortunately not enough to get any medical seat. You can try for private medical colleges or try again next year.

Good luck 

At 275 marks you may not be able to get a good college of your choice.
You can try for private colleges.
