Hi Smita,

If there is a single letter misalignment in your passport-size photo and your postcard-size photo had the proper name on it, the NTA has no obligations to auto-correct. NTA relies on the data entered in the application form, and expects candidates to correct errors or misalignment during their correction window. Because you didn't correct it during the correction period, the error may persist to the final admit card or record.
If your application details align in the other specifics (like ID proof, name on form or other data), having one misalignment in singular images should not automatically exclude you from the exam. That being said, you should call the NTA helpdesk, or even observe for official updates if they give opportunities to correct these misalignments.
