If you were unable to upload your rectified NEET document within the designated correction window timeframe, it is highly unlikely that you will be given a second chance to upload it as the NTA (National Testing Agency) usually does not reopen the correction window once it closes.

Reach out to the NTA through their official channels like email or helpline number to explain your situation. While unlikely, there might be a rare circumstance where they might consider a late submission if you have a valid reason and supporting documentation.

Regularly check the official NEET website for any announcements regarding potential extensions or correction window re-opening, although this is very uncommon.

If you cannot rectify your document, you might need to consider preparing for the next NEET 2025 exam if you still wish to pursue medical studies and remember to fill your documents properly to avoid another rejection.
