## 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.

## 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).
