Hi Jyoti, 

That should not be a p roblem as far as your upcoming examination and declaration of results are concerned. However, it is ssuggested that you call up at NATA or write an email to them informing about the same. Moreover, this issue will arise at the time of counselling, so be prepared beforehand for the situation. Writing an email would also be a proof that you had communicated this to the concenred authorities as early as possible. If there is anything else, please let us know .Keep reading Careers360 for more updates on JEE MAINS, 2019. Use the link given below:
