Mam are you sure that it will not effect during the exam time or at the time of counselling and admission?  I am very worried about it mam please clear me out regarding this.

Dear Rutika, your Mother's name doesn't affect your merit. Say if your mother's name was Suchitra Patra and you wrote Suchi Patra, it doesn't affect your Rank and Merit list. So, this is not something that needs maximum attention during your admission and counselling. But say if your category is General but you mention OBC, then it is an issue because it affects your merit list. I would say, worry not and concentrate on scoring a good rank. Good luck!

But mam the mistake is I have entered my father name instead of my mother name will this affect during exam and counselling?

Please reach out to the helpdesk. It needs to be corrected. 

Mam how can I correct that? please help me.  

Dear Rutika, as much as we understand your situation, we can only suggest you to reach out to the helpdesk. The correction window could have benefitted you to change those details. But now, its too late. We can only hope the Helpdesk helps you out.

Rutika Patra Hy so what happened at the last Because I did the same mistake and now I'm scared cause I can't do anything about it
