Hello aspirant,

Hope you're doing well.

Kalasingam university offers btech programme in 14 different disciplines. So yes, you can pursue btech from this university in Tamil nadu. Selection criteria is TNEA exam. However, I don't think that there are any courses offered in the economics discipline. However, MBA in acturial sciences is there. You may follow the link provided below for further assistance:
