Dear Sir / Ma'm, the JIPMER entrance examination authorities do not have any correction window for correction in the application form to rectify the mistakes which might have occured during the registration. You may do one thing that is call on the helpline number available on their website and cite your problem. You can also reach the examination centre on the day of examination a little early so that you can talk with the authorities over there and do no forget to carry valid identity proof so that you can show them your correct details.
