Dear aspirant,

I'd suggest you to carefully understand these informations I'm providing.

If NEET authorities don't notify you to change anything, than you just can't change any scanned photo copies that you have already provided. It means whatever photos you have provided is approved by NEET authorities and you have nothing to worry.

But if you have made any mistakes in providing personal details than you can change them without being notified. Let it be your address details or parents name, if you have made any errors there, than NEET authorities will not notify you about that. You'll just have to visit the NEET website and change whatever wrong personal details that you've provided.

Hope this helps you!
