Hi !

You can't do anything regarding the appearance of your name in the AIIMS merit list. The merit list has been prepared by AIIMS after calculating and considering marks of all the students who appeared for the examination. If your name is not appearing in the  first merit list, it means you could have scored low in the exam. Maybe your name will appear in the subsequent merit lists. 

You can only wait and hope for the best !

The merit list is in the hands of AIIMS and nobody can object that.
