If you have filled your NEET form as per your Aadhaar card but your Class 10 marksheet has different details and the correction window is now closed, you can still appear for the NEET exam without any issue, so don’t lose focus after all the hard work you’ve put in; however, there is a possibility of facing problems during document verification or counselling if the mismatch is significant (like name, date of birth, etc.). For now, the best approach is to stay calm and give your exam with full confidence, because your preparation matters the most at this stage. Also, take this as a learning; always ensure all documents are consistent before applying.
