Hello Aspirant!!

Like NEET, JEE, there won't be any correction window for TNEA counselling conducted by Anna University.

As you are from Tamil Nadu only, so they know that the maximum marks will be 600 only. I think this is not such a big mistake. Even though, if you feel that you are so confused and you are wanted to be relaxed, visit the nearby TFC center to your house. Take your Aadhar card with you. They will provide you a correction form, you can edit your changes in it.

It will get reflected within 3 days in the website.

hope this helps you!

Best of luck!
