Dear aspirant!!

Hope you are doing well ! Nothing will happen so unique ,many students has done the same thing but later all of them will face issue . . Now you will face problem as you shouldn't do that, may be as it has seen in past years that students with this mistake don't get their rank . So its my suggestion to you to please call or email NTA and talk them properly about your problem . Now this is the only option . We also can't help you in other way .

Hope it helps you !

Thanks
