In case you want to know more about GATE exams then read my article on that. In that article you can post your questions regarding Eligibility criteria, exam format and other details important for you.I have also shared complete details about the exam as well.
GATE Electrical Engineering Statistics
Below are some interesting statistics about this paper
- Number of candidates registered for the exam – 1,50,000 (approx)
- Number of candidates appeared for the exam – 1,30,000 (approx)
- Number of qualified candidates – 21,396
- Percentage of candidates qualified – 16% (approx)
- Maximum marks out of 100 – 88.39
- Minimum marks out of 100 – 16.74
- Average marks – 34.09
- Standard Deviation – 11.17
The pass percentage of this paper is lower compared to most GATE papers. On an average most GATE papers have pass percentage of 20. This paper has pass percentage of 16. This makes it one of the difficult papers to clear GATE exams.
The number of candidates appearing for this paper is lower only than Mechanical Engineering and Electronics and Communications.The average marks is also low only 34 marks. But the highest marks is 88 and lowest marks is 17. So majority of candidates have marks in range of 25 to 45. So if you can get any marks above 50 or 55 then you will have decent rank.
Based on above discussion you can plan your preparation.There is no need to cover all the topics.You can cover some topics important for exams which will get you 50% of marks. Quality of preparation is important than quantity.Below preparation materials will help you crack the exam with ease.
GATE Electrical Engineering online tests
The best GATE Electrical online test series created with quality in mind.The sole focus was to create a test series which give you edge over other candidates.It should be one of the tests in huge collection of online tests.Rather it should be a distinct test which help you crack the GATE Electrical Engineering paper with ease.
Below are the links to GATE Electrical Engineering tests.Note all the tests are unique and totally free.For best results you should try all the tests.
You can also compare your marks with that of others.So you can know your preparation level to that of others appearing in the exam.If your marks is on higher side then good if not then you need to invest more time studying.
GATE Electrical Engineering recommended books
Electrical Engineering is core branch of Engineering.So there are lots of book available in the market on this subject unlike some of the GATE papers.Out of them it was tough job to select a book.Some of them were close competitors and it would not be justice to say this one is better than other.But taking everything into account along with students feedback I came up with below book.
This book contains Theory (in short) , Practice sums (about 40-45 sums coupled into 2 exercises level 1 and 2 after every topic) , Gate previous year problems (about 20 per topic) , a subject test at the end of the subject.Overall it has a good number of quality questions to aid your preparation.
The book is divided into three parts covering, (1) General Aptitude, (2) Engineering Mathematics and (3) Electrical Engineering. Coverage is as per the syllabus prescribed for GATE and topics are handled in a comprehensive manner.The book has 1700+ solved questions, 6000+ practice questions and Question Bank Covering Previous 10 Years GATE Questions Papers.
The book has theory part as well in concise manner ideal for revise.You can buy the book at discounted price from below link.
GATE Electrical Engineering syllabus
GATE Electrical Engineering syllabus comprises of most core topics of Electrical Engineering curriculum covered in Graduate courses.So if you have books of those core subjects then they will help you in preparation.But you should also understand which topics are included in GATE exams and which are not.This helps in better planning and preparation.Wasting energy on subjects which will not be part of GATE exams is not good.
Below syllabus is latest one taken from the official website of GATE exams(link).
