Hello Tharani Mani!!

Actually, you have entered the school of study as government in TNEA application form.

As of like JEE , NEET exams there won't be any correction windows for TNEA.

So, to rectify from this trouble you can visit to the TFC center which is nearby to you, and tell your query. They will rectify your problem. While visiting the nearby TFC center, you take your Aadhar card with you.

They will give a correction form in which you can edit the information. The edited information will change in the TNEA website within 2-3 days.

The list of TFCs and the contact details of each TFC are given in the official website of TNEA.

Hope this information helps you.

BEST OF LUCK!!
