Hello,

Well, please mention the name of the exam or course in which you want to change your name. 

Good luck.

Dear Srita, you haven't mentioned the name of the exam. Hence we are giving younthe general information. Now most entrance examinations give you a correction window. This correction window opens once the online application closes. During the correction window, you can make the changes to your name. However if there no correction window, you will have to reach out to the concerned examination helpdesk as how to solve this issue.
