Hello Abhay, 

            For your information  no changes can be made in the NCHM application once submitted.

       Also the exam is over, the results are out and the 1st round of counselling has already begun.

     These things (filling up application form) are very crucial things and need utmost attention and knowledge as the information should be valid and true as u have to submit a proof of each amd every information later during counselling failing which may result in rejection of your application.

  Good Luck
