Hello Kaash,

If you've entered the wrong total marks but the individual subject marks and supporting documents are correct, it may not cause a major issue initially. However, any mismatch during document verification can lead to problems.

What you should do:

1. Contact TNEA support/helpdesk immediately via their official email or helpline.

2. If portal correction is allowed, update the marks as soon as possible.

3. Carry all original documents during counselling for verification and explain the mistake if asked.

It's always better to correct such details in advance to avoid disqualification.
