Hey Aastha
Well nope, this is not possible as document verification is the most important process.The all India rank and the category ranks have been up and cannot be changed. All the documents are verified, and the data of verification is then entered and saved for future references. Some authorities might accept your wish to change it( you have not mentioned the examination for the same). You may try to contact them or write an email stating your problem.
I hope this helps. Feel free to ask any other queries.
