Hello student,

In order to get these college through NEET UG your NEET score is little bit less than thier cutoffs for EBC category. 

For IGIMS you should have a score of 558 marks whereas for DMCH and NMCH you should have a score of 553+ marks.

So, it will be difficult for you to get a seat in these college with  a score of 540 marks. 

Hope it helps. 

Thank you  :)
