A new paper "Statistics" has been added this year, taking the total number of papers for which GATE 2019 will be conducted to 24; in the last edition of the exam there were 23 papers. The candidate though will be able to appear for one paper only, preferably in a paper related to the candidate's qualifying degree; that being said, the candidate is free to choose any of the 24 papers. IIT Madras has released the admit card of GATE 2019 on January 4. The GATE 2019 application form opened on August 31, 2018, and had to be filled through GOAPS (GATE Online Application Processing System). Last date to submit completed application without late fee was September 23, 2018. With late fee, the application form could be filled till October 1, 2018. Registered candidates could submit the application form till October 3, 2018. Correction facility of application form for all registered candidates was open from September 27, 2018. It must be noted that to be eligible for admission to M.Tech courses offered by various institutes based on GATE scores, candidates needs to qualify in the exam. The qualifying score is different for each paper, and has been released alongside GATE 2019 result. Also, unless the candidate qualifies in the exam, GATE 2019 score card will not be available for download.
The validity of GATE 2019 score card will be three years from the date on which results have been declared.
Graduate Aptitude Test in Engineering (GATE) is a nationallevel postgraduate 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 programmes offered by government as well as many private institutes.

Mode of Counselling: Online
Interestingly, while IIT Madras is the exam conducting body, it will not conduct any common counselling for GATE 2019. The candidate instead will have to apply separately for admission to M.Tech courses offered by various institutes based on GATE scores and ranks. In case the candidate wants to take admission in an IIT, he/ she will have to register on COAP, and also apply separately to the specific IIT. All offers made by participating institutes will be uploaded in the COAP portal; registered candidates in turn can accept or reject offers on the portal.
For admission to NITs, counselling is commonly done through CCMT.
What is GATE COAP 2019?
The GATE Common Offer Acceptance (COAP) was started in 2017 by the IITs as a common admission platform for making admission offers to candidates. So, while the candidate still needs to apply to an IIT individually for admission, he will only know about any offers by registering on the COAP portal. Also, the acceptance or rejection of offers can be made only through COAP.
Admission to IITs is a twostep process:
 Apply to an IIT (or IITs): The candidate has to apply to the IIT based on their GATE scores.
Register on COAP to view, accept or reject admission offers. Based on the applications received by the IITs, they will make all the offers on COAP portal.
Note: COAP is not an application portal, but instead an admission portal.
CCMT:
Admissions to the postgraduate programmes will be through CCMT which is the Centralized Counselling for M.Tech/ M.Arch/ M.Plan admissions at the NITs, and other GFTIs.
Documents Required at Counselling
