Dear Anamya, if this is regarding, JEE Mains Application, then you neednt worry about it. There are 2 ways to go about it. NTA will open its correction window from October 11th to October 17th. NTA will notify those Candidates whose photograph and signature do not match the criteria at their registered email and mobile number. Such Candidates will have to make those necessary changes. If you don't receive a notification, then you are good to go. Your application will not be rejected for this reason. Alternatively, you can mail the helpdesk. Keep an eye on your registered email id and mobile number for any such notifications.
