Hello, 270 in NEET is a low score to get admission into any of the medical courses. To get admission into MBBS it requires a very high NEET scores i.e. 550 and above scores for general category. For reserved category the NEET scores should be at least in the range of 490-550. These scores are still very high than the score you are expecting. I suggest that your child should start the preparation for next year's NEET from now with a lot more hardwork and confidence. 

All the best!
