GATE 2020 Preparation Tips

ddddd

Being a national-level exam that is attempted by more than 10 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 2020 Mock Test

The exam conducting authorities are expected to release GATE 2020 mock test 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

GATE 2020 Counselling

Mode of Counselling: Online

Interestingly, while IIT Delhi is the exam conducting body, it will not conduct any common counselling for GATE 2020. 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 2020?

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/she 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: IIT 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. Candidates have to fill the application form on CCMT to be conducted by one of the NITs, fill their choices of courses and institutes and after the seat is allotted on the basis of their GATE score, they must complete admission formalities if they accept the seat.

Documents Required at Counselling
