GATE 2019 Preparation Tips
Being a nationallevel exam that is attempted by more than 9 lakh candidates, the level of competition associated with GATE is very high. Also, the exam in itself possesses many tricky questions meaning success hinges on not only how hard the candidate prepares, but also the how of preparation. Here are some preparation tips the candidate can refer to to give edge to their success efforts.
 Make sure you are familiar with the exam pattern and syllabus. Or else you will get too many surprises on exam day which may be not to your liking
 Get surrounded by reliable study material
 Don’t put yourself under the pump by thinking too far ahead. Stay in the present and focus only on your preparation
 Make a preparation plan and stick to it
 Take notes during study. It will not only keep you focused, but with a little effort you will be able to build a solid and customized reference material. It will also come in very handy in the final days leading to the exam, as you won’t have to go through huge blocks of text.
GATE exam pattern 2019 will tell the candidate whether the test will be conducted in online or offline mode, type of questions asked, distribution of questions, number of questions asked, etc. which are essential details for thorough preparation for the test. As per the GATE 2019 exam pattern, all 24 papers for the exam will include a compulsory General Aptitude section carrying 15 marks.

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 paperspecific. 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 login 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.
On exam day, candidates need to bring an original and valid photo Identity proof along with the admit card; or else they will not be allowed to take the exam.

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 subjectspecific 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 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.
