BHU UET/PET admit cards have been also released and  not it is too late for any corrections. But if you belong to EWS Category and you do have the necessary documents to prove so, you will be fine. This is because any annual income less than 8 lakhs from all source can be considered under EWS Category provided you belong to General Category and are not availing any other benefits pertaining to those of OBC,SC,ST. Your EWS Certificate is a proof that your household income is less than 8 lakhs per annum and that should be fine. So do not worry about that. During document verification it is the EWS Certificate that you have to produce and not the Bank Statements and so you will be fine.
