## How to Prepare for GATE Electrical Engineering?

Stay motivated

To prepare for GATE 2021, make sure that you do it strategically. Without any plan, your preparation will be all over the place. You will be confused as to what topic to do next or you might skip from topic to topic that will make it difficult to complete a single topic properly. For this reason, you will require a plan that you can follow strictly. Along with strategy you might need some additional help. For this purpose, we have given a few preparation tips below that you must keep in mind during your GATE 2021 preparation.

Exam Pattern

Before starting your preparation, go through and understand the exam pattern, marking scheme and the syllabus of the exam. This will familiarize you with the question paper. You should know what type of and how many questions will come in the exam, how is marking done, what sections will be there in the exam, etc. In short, it is like going through the summary of a book. It is essential for you to get an idea about what you are supposed to prepare for.

Prepare Schedule

Procrastination will not help you prepare for the exam. You will have to make a study schedule that you are supposed to follow honestly. The schedule will teach you discipline that is very important if you are aiming to score high in the exam. Your schedule must allow sufficient time to each topic depending on your preparation and your aptitude. Also, leisure time should be included in that schedule so that it doesn’t get hectic for you.

Fundamentals

It is essential that you seek thorough knowledge of the fundamentals. Your focus should be on gaining concept clarity. Understand the basics and practice them simultaneously. For conceptual knowledge, the best material is the standard books. The language used in such books is really easy to understand and learn. It is the best way to make your foundation strong.

Mock Tests

You must prepare thoroughly through the mock tests. And even after you have completed your syllabus and preparation, take full-length mock tests at regular intervals. It is not only important for preparation point of view but it will also make you familiar with writing the exam online and also using virtual calculators. Mock tests will also enable you to practice time management quite well. Get so used to giving the mocks, that GATE 2021 appears like a mock test too. This will also settle your nerves during the exam.

Revision

As you proceed towards the last month, start revising all the topics in your syllabus one by one. At this point, you will need all the notes that you prepared throughout your preparation. Go through all the pointers and formulas that are in the notes. All of these will help you recall all that you have prepared in the past few months.

## GATE Electrical Engineering Books for Preparation

Candidates are advised to choose the study materials carefully. Some books might confuse you more than giving you any substantial knowledge of the concepts. To avoid such a scenario, pick books from renowned authors and publications. You can also pick the books we have suggested below.

## What is Electrical Engineering?

Electrical Engineering is concerned with the study, design and application of equipment, devices and systems utilizing electricity, and electromagnetism. The said discipline is divided into a wide range of fields including Computer Engineering, Power Engineering, Radio-frequency Engineering, Telecommunications, Signal Processing, Electronics, and Instrumentation. Most of them overlap other engineering branches, spanning a large number of specializations such as Hardware Engineering, Microwave Engineering, Nanotechnology, Mechatronics, etc.

## GATE 2021 EE Preparation FAQs

Q1. How to prepare for the Mathematics section in GATE 2021?
Ans. The Mathematics section requires a lot of practice. You must learn all the formulas but don’t rely solely on them. Take mock tests of each topic and also full-length mock tests.

Q2. How to prepare for Verbal Ability if it is your weak area?
Ans. Try to read as much as you can. To ace this part of General Aptitude section, you will require a wide vocabulary that can only be achieved if you read regularly. Practice and learn all the grammar rules.
