GATE 2020 Preparation Tips
Being a nationallevel 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 exam pattern 2020 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 2020 exam pattern, all 25 papers for the exam will include a compulsory General Aptitude section carrying 15 marks. The full details of the exam pattern are described in the tables below.

The exam conducting authorities have released 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 is paperspecific. So candidates appearing in, say, Aerospace paper, need to take the mock test specific to it only.
 The test includes 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

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 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: 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
 Self attested copy of GATE score card (2018 or 2019 or 2020)
 Photo ID proof as per government of India norms

Questions related to GATE
I want to prepare for GATE in Petroleum engineering
Hello dear student,
I understand your query and I would like to tell you as you want to prepare for GATE you really need to have a good grip on aptitude so prepare for Aptitude because there comes aptitude questions where you can secure easy marks. While we can go to the syllabus for this trade that comes in GATE and you can prepare accordingly. while I would suggest you to solve previous year question papers of this trade and also try to solve MCQs because that will help to gain marks.
I hope this was helpful
Best wishes
what is the use of gate exam??
Greetings!
 Graduate Aptitude Test in Engineering i.e.GATE is a computerbased standardized test conducted at the national level in India with an aim to examine the understanding of various engineering and science undergraduate subjects.
 The use of GATE exam is that it is for admission to M.Tech programmes offered by government( like iit , nit etc) as well as many private institutes. You can use your GATE scores for admission purposes in the IITs through the Common Online Admission Portal (COAP) for IITs and CCMT for NITs or even apply to leading PSUs which recruit on the basis of the same.
 It 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.

Thankyou
given a and b input terminals logic 1 is equals to get in 5 world logic zero is equals to less than 1 volt which logic Gate operate the or does
It is a standard considered in electronics that 5V power supply is logic 1 and below 1V is logic 0. This because the ICs and other equipments can handle minimum of 5 V to work . If it goes higher than the LED will burn out same goes to other equipments too. If they get any voltage below 1V it won't work and it will become dead which is a sign for 0 logic.
It is NOT gate. If any value less than say 1 becomes 0 and any value is greater than 5 becomes 1. There is a threshold value in it which is a constant. NOT gate only knows that logic value and reverses it in output.
Hope it helps you
After clearing gate in statistics subject what are career options???
After clearing gate in statistics subject, the options with you now are Software Development, analytics and actuarial science. At the same time, you can also go on for Indian statistical options, civil services and Indian Economics services exams.
Statistics and the analytical skills are in high need in today's world in India as well as foreign.
Thank you.
Yes, I am a mechanical student pursuing last year. I am prepare for GATE 2020. but I wanted to ask you that, actually I have a 3year gap in academics so, even if I am getting good marks in GATE 2020, will my gap effect to get a good positional job in the industry?
Dear Aspirant,
Mos of the recruiters allows a academic gap of 3 years at maximum. So if you have 3 years of academic gap, then you will be okay with most of the companies. However, if you have total gap more than that then it will shrink your opportunities but that does not mean you'll not get a job. It is just some recruiters won't allow you.
Hope this helps. Thank you.
