When I tried to upload +2 marks for amritha, I received that the application number and DOB doesn't match with our records. Pls give the answer as early as possible, there is no more time.

Hello aspirant, there might be a possibility that your actual dob is different from the one you have in your certificates. If this is the case, enter the details as per the records in the certificates. Another possibility is that dob might differ in your birth, 10th or +2 certificates. Make sure there are mo discrepancies in dob. If these two cases are not there, then there might be a technical problem from their side, they would have given mobile number or mail I'd. Kindly contact them. They can help you with this
All the best
