Dear Pritilata, The correction window should be open from January 23rd to 25th. Please try making changes to your application in the required fields then. And the Supreme Court has passed on an order stating that Aadhar card details are not mandatory for accademic purposes. So if you gave any other Id proof details along with Aadhar card details, you are good to go. However, if you have only selected Aadhar as the Id proof, try changing it during the correction window and in case you are not able to make chamges, reach out to the helpdesk.
