Hello aspirant, 

Well it can affect you in counseling if you have mumbled up with things that could change your category, for e.g. If you have put the wrong income and it changes your category from UR to UR EWS then it could be a problem. 

Or if the occupation misleads the category or anything else important then it could be a problem.

I would be able to tell you better if I knew exactly what mistake did you make. 

Let me know if any queries. 

Thank you
