Hello Arushi

If you were allowed to appear in Neet with all these documents then there is no possibility that you will face any issue.

You must have made changes in all other documents for your surname,  .

Now also you can make changes as Aadhar card is showing the correct spellings .

In government offices you may get edited these documents on the basis of aadhar card . Do it as soon as possible that you won't face any difficulty in future for  your further studies .
