Hello Shubham,

Graduate Aptitude Test in Engineering (GATE) is a national-level post-graduate entrance exam that is jointly conducted by the seven IITs (Bombay, Delhi, Kanpur, Guwahati, Kharagpur, Madras and Roorkee) and the Indian Institute of Science (IISc), Bangalore for admission to M.Tech programs offered by government as well as many private institutes.

GATE 2019 was organized by Indian Institute of Technology (IIT) Madras in online mode on February 2, 3, 9 and 10, 2019.

IIT Madras is only the conducting authority of GATE 2019 exam and will not conduct any counselling for the admission.

As for your question, there is no particular reason, it is just that the internal procedures would have taken more time.One more reason could be the new EWS category that has been launched by the government, which would require PSUs to recalculate the number of seats.
