Hello Aspirant !!

As per the Tamil Nadu Website, you can either post or courier the application to the address mentioned by you . Though , you can take the risk of going to the above location but whether you will be able to deliver it to the right person or will this be acceptable is questionable .

I checked in Google maps and the above address exists .

Please type -  "162 Periyar , High Road , Kilpauk  "  in the search box of Google maps and you will find it .

To

The secretary 

Selection comittee  is the address you need to mention in the post /courier .

All the best.

Hope this helps .
