# Updated GATE 2019 Syllabus – Electrical Engineering

As all of us know that these days all PSUs recruit as per the GATE rank so it is very important to secure a good rank in GATE Exam. I will strongly recommend to study with a proper strategy to have a great rank. I will soon post on how to make your strategy for GATE Exam.

In this post I am just putting the syllabus of GATE-2019 for Electrical Engineering. So go through the Syllabus and make your plan. But again, I will say to take a print out of the syllabus and paste it on the wall of your study room and as your study a particular topic, mark it by pen in the syllabus.
