I too am having the same issue this year...could u plz tell me if I will be having any problem with my seat allotment or councelling for the same mistake ?

In most of the cases if you enter any wrong information and it doesn't match with your supportive document they raise discrepancy and within a stipulated time you get to remove that. Other than that at the time of document verification there is still a chance to resolve your mistakes most often. Keep yourself updated with any latest information regarding correction and follow your mail regularly.

Good luck!!
