About GATE 2019

GATE 2019 will be organized by Indian Institute of Technology (IIT) Madras in online mode on February 2, 3, 9 and 10, 2019. 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. 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 is now 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 will be different for each paper, and will be known at the time of declaration of 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.

The exam conducting authorities has released GATE 2019 mock test on October 30 to help candidates get familiar with the functionalities of the online exam. A simulation of the real exam, some of the key features of the GATE mock test include:

  • The mock test will be paper-specific. So candidates appearing in, say, Aerospace paper, need to take the mock test specific to it only. 
  • The test will include similar types of questions to the ones asked in the actual exam. So taking the mock test will help better understand the exam and get rid of exam fear.
  • The status of questions, for example – answered, unanswered, and marked for review, will be displayed in the different colour palette. 
  • The mock test of GATE will have two sections – subject specific section and General Aptitude section
  • The candidate will be able to navigate between sections and from one question to another using specific symbols

IIT Madras will issue the admit card of GATE 2019 in online mode on January 4. To download admit cards, candidates need to log-in to the GOAPS portal using their enrolment or email id and password. Before downloading the admit card, check for any discrepancy, in which case the candidate needs to get in touch with exam authorities to get it rectified.

The top coaching institutes will come up with paper-specific GATE paper analysis after conclusion of the the exam. The GATE 2019 paper analysis will include expert analysis of different parameters – like the overall and section-wise difficulty level of the paper, the expected qualifying cutoff for the paper, and whether there were any incorrect questions asked. The GATE paper analysis will therefore help the candidate make a fair assessment of his/her chances of admission.

The candidate may also go through exam analysis of previous years to get insights into the exam, which will be useful for exam preparation.

Soon after conclusion of the exam, the answer key of GATE 2019 will be released by various coaching institutes like Made Easy, GATEForum, and Engineers Academy. The GATE 2019 answer keys will be released for all 24 GATE papers and include answers to questions asked for the specific paper. Candidates can compare their answers with those given in GATE 2019 answer keys to calculate the number of correct responses and thereby probable scores; the marking scheme of the exam has to be used for calculating probable scores. IIT Madras will release official GATE answer key 2019 tentatively in the 3rd week of February.

The qualifying GATE 2019 cutoff is the minimum marks that a candidate has to score to qualify in the examination. The qualifying cutoff will be subject-specific and will be released alongside the result on March 16. Please note the qualifying cutoff for GATE 2019 is not the same as the admission cutoff which will be determined by institutes for admission to various M.Tech courses offered by them.

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 two-step process:

  1.    Apply to an IIT (or IITs): The candidate has to apply to the IIT based on their GATE scores.  
  2.    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.
