Graduate Aptitude Test in Engineering (GATE) is a kind of examination that basically tests the thorough understanding and the caliber of students of various subjects that are taught to undergraduates in engineering. GATE is conducted jointly by the Indian Institute of Science and seven Indian Institutes of Technologies on behalf of the National Coordination Board – GATE, Department of Higher Education, Ministry of Human Resources Development , Government of India. ECE is the only branch which has an important role in all PSU, DRDO, ISRO etc. hence appearing for GATE would provide students with good opportunities.
Eligibility for GATE ECE Exam
- If the candidate is pursuing any higher degree or already obtained a degree higher than that mentioned in the above table, then the candidate can select the minimum required qualifying examinations, then the candidate can select the minimum required qualifying degree while filing GATE application form.
- In case, a candidate has completed one of the qualifying examinations then they have to submit the degree certificate / provisional certificate/ course completion certificate issued by the institute.
- There is No Age limit.
Cut-Off for GATE Electronics and communication engineering Exam
The cut off marks varies every year but not by a big margin. Here is the cut off of previous years by which the changes expected in the next exam can be analysed.

GATE ECE Preparation Tips
Cracking GATE examination requires proper strategy, determination and focus. It requires constant efforts towards the subject in clearing up the basic concepts to obtain good marks. Just mugging up the concepts will not help you score well, rather you must focus more on the understanding part with practical approach of the subject. Strategic preparation, time management, smart study are a few key points. The tips are elaborated below that would help the aspirants to crack the examination.
1. To start with, candidates must be aware of the GATE exam pattern for EC engineering completely
- It consists of 65 questions out of which 35 questions are of 2 marks and 30 questions are of 1 mark with a total of 100 marks. Candidates must know that there are only two types of questions, multiple choice questions and numerical answer type.
- They should be aware that there will be 2/3rd negative marking in 2 markers and 1/3rd negative marking in 1 markers whereas there is no negative marking in Numerical answer type questions hence only they can get the maximum numbers in the test.
2. Know the syllabus of EC engineering and the weight-age
- It is suggested that the candidate goes through the complete syllabusbefore starting the preparation. Match your knowledge with the exam syllabus and plan your preparation with known subjects.
- Highlight the important topics in the syllabus based upon the previous year papers and focus more on these topics during the course of your preparation.
3. Choose good books & study materials related to EC engineering for the preparation
- Selection of appropriate and concise study material is very important before starting the preparation.
- Read at one book apart from the study material which is provided by your institution and your class notes.
- Nowadays the whole package is available online in the form of video lectures, course materials PDF, so you can pursue best study material.
4. Study smartly during the preparation
- Analyse important topics and pattern of questions from the previous year papers which have been provided with for reference.
- Prepare each topic in three steps. Understand the concept, practice related questions and revise regularly. This will help you to analyse your preparation and also boost your confidence.
- Most of the questions are conceptual & numerical, so you must try to improve your solving ability and time management to score a good rank.
5. Prepare the study plan to complete the syllabus
- The first step in the preparation is to start with easy subject and important one that has been mentioned below. Segregate whole subject into smaller topics and prepare topic wise
- After completing the subject, make short notes for that subject which should include definitions, important formulas etc. This will help during the time of revision.
- Clearing all the doubts during the preparation is essential.
- Identify weak areas while practising tests and try to revise and practice those topics.
6. Proper revision plan
- It is not just sufficient enough to prepare revision notes, but also to revise them regularly.
- Read the revision notes on a weekly basis to recall the concepts of prepared subjects.
- Each time you revise the same topic/ subject, your revision time will reduce to recall the concepts.
7. Mock tests and practice papers
- Mock tests play an important role.
- Firstly, it gives you an exam like interface. This is very important for any aspirant, to have idea and thorough practice on exam like interface.
- They provide All India ranking, so you know where you stand.
- Test analysis about how you performed in exam and how toppers have performed, which helps you to analyse and understand how much more preparation is required and on which area.
- You also get to keep a check on which question was easy and you couldn’t attempt, but attempted a tough question which was expected to be left. And how much extra time have you given to that particular question.
- Comprehensive explanation to every single question coupled with smart tricks/intuitive approach in the form of text, Images or both.
- From mock tests, you get to know your strength and weaknesses in a well-defined manner.
- Tests in general are important. They help not only in the assessment of your preparation for exams, but also regular test attempts help you memorize better.
