Hi there

According to the National Testing Agency, which upholds the exam and AICTE the technical committee under which engineering domains have conferred on the case of any form of engineering to be possible through entrance examination, now that examination could either be JEE if you're planning to go for central institutions and majority state universities, or as it the case with some state universities and private colleges you could give their examinations. You'll have to look up on the brochure of the institution you're aiming to study in for more clarity.

Hope this answer helps; best wishes
