I have verified my documents in the 1st round counselling of up for state quota and i have not alloted to any college now in 2nd round
NO you need not to re verify the documents, all what you need to do is to go with the process. The reason behind your college not been alloted is due to you have not listed the appropriate colleges and courses as per your rank. So wait for it and participate in the rest rounds. Otherwise try for spot round with more options.
