Greetings !!

Once you have given final submit, then you can not edit the details in SSC Portal. All the changes has to be done before final submit. At the time of document verification if any differences found, the panel would ask for clarification. At that time if you are able to justify the same with valid documents, it won't be a big issue. Stay focused, prepare well for the exam. If any doubts, pls feel free to ask.

Wish You All the Best.

Thank You !!
