Girija, NEET has a one time correction facility. NTA has opened its correction window from January 15th and shall remain open until January 31st. You can make changes to your Date of Birth. Login to the official website: ntaneet.nic.in with your NEET registration number and Password. Now click on " Correction in NEET application form" and make the desired changes to your application form. Any correction pertaining to the photograph and signature of the candidate will be intimated through e-mail/SMS and the same will be available in the candidate’s login account. Rest of the fields like Father's name, Mother's name, Date of Birth, Category, Gender can be changed during the correction window. Once the correction window has been closed,  NTA does not guarantee that any request for change in information will be entertained. So it is the best thing to make a note of all the corrections that you need to make when the correction window opens from January 15th to 31st and click on the "Final Submit" only after making all the changes that you want to. Once you click on "Submit", enter the OTP number and take print outs for future reference.

Now it is not clear whether you have used the correction window  or not. If you haven't used the correction window yet, please follow the procedure mentioned and make the necessary changes. But if you have already used the correction window once, you cannot use it again and NTA doesnt take responsibility and make the corrections on its own. Even if you get an admit card during entering the exam hall, because you have to show some id proof and there will be a mismatch in the Date of Births, you may not be even allowed to the exam hall.

Hello!

Yes, unfortunately it is a problem. When you get into your desired medical college or maybe when you have to present your documents like birth certificate, Aadhar card and other such, it will become a problem as the authorities are strict with all the procedures! All you can do is try to contact the authorities in order to look into this matter completely!
