No. Let's say you make changes in your NEET application form, now once you click on Final Submit, you will get a confirmation page. That is the proof that your request for corrections have been accepted and the changes have been made because that is the reason a correction window is made available in the first place. They will reflect on your application. Now these changes will reflect on your Admit card as well depending on the details that you have made changes to. But let's say for some reason the changes do not reflect on your admit card once you receive it, you need to immediately reach out to the helpdesk. And NTA will make a note of these changes that did not reflect and shall intimate you that these will show up on your NEET application form and then the counselling registration should you qualify in NEET. And you will be still allowed to appear for the exam. NTA will look into that. But truth be told, you making changes and they not reflecting on the application form are very minima. So do not worry about it. And if you are preparing for NEET, you may as well try our NEET Knockout package: https://learn.careers360.com/knockout-neet-may/ .
