Hii aspirant
Hope you are doing well amid covid-19 pandemic
The problem with you is that the NEET exam is knocking the door and your admit card is having a mistake, your father name is wrong
If the mistake was commited by you during filling of the form then the correction window is over you cannot get it corrected online but if the mistake is in their part NTA you can carry the valid id-card with you, usually NTA does not commit mistake'in father name or Date of birth, sometimes they make mistake in adress
Like now you have not filed the form properly and correction window has expired you can send a mail to NTA with the admit card and valid ID proof and ask for solution and do it as quickly as possible
The email id is as follows
neetug-nta@gov.in
