Hey there, you have scored 264 marks in NEET. If you are looking for good medical colleges at these marks then sorry to say but you will not be able to get that as your marks are quite low for that. If you are looking for admission for another chance for NEET then yes you can drop. But still, at these marks, you can even get admission in some good colleges too. 

I would rather suggest you check the colleges available for you at these marks at College Predictor at Careers 360 only and it will be very helpful for you while getting a seat there. It will be very helpful for you as it will show the best colleges available for you according to your category and even home state rank.
