The GATE Exam is one of the most prestigious exams in the country. A perfect opportunity to not just pursue higher studies from some of India’s top colleges but to also get a job with one of the PSUs; GATE exam has it all. As such, it is no wonder that so many people are looking at the GATE exam 2019 with dewy eyes.

In continuation to our GATE 2019 syllabus series, today we will be looking into and discussing about the GATE syllabus for ECE. And, not just the syllabus, in this article we will also introduce you to the type of questions you can expect during the exam, best GATE exam 2019 preparation books and a brief GATE exam preparation guide.

 

 

GATE Exam syllabus – General Aptitude

The General Aptitude section of the GATE exam holds a 15% weight and is as such an important part of the GATE exam 2019. Though not particularly tough, the General Aptitude section is known to be tricky.

Furthermore, this section is divided into two parts – Verbal Ability and Numeric Ability.

Verbal Ability

  • Verbal Analogies
  • Verbal Deduction
  • Sentence Completion
  • English Grammar
  • Critical Reasoning
  • Word Groups
  • Instructions

Numeric Ability

  • Data Interpretation
  • Numeric Reasoning
  • Numeric Estimation
  • Numeric Computation

How to best prepare for GATE Exam 2019

Before you start with your GATE exam preparation, you should get a thorough understanding of the syllabus, see which topics you might face the most issue with and which most and then divide it accordingly. Now –

Work on a timetable

We cannot stress enough how important a good GATE Exam timetable can be. A thorough exam timetable can help you keep track of your improvements and progress. It will also remind you when you are not doing enough to prepare well for the GATE exam 2019.

Your timetable should be more like an exam plan of how you will proceed along the syllabus, which topics you will cover first and in how much time. Also, specific time should be laid out for revisions to fortify your GATE preparation.

 

Attempt sample papers

If you truly want to succeed at the GATE exam 2019, then you will have to make sample papers a part of your daily or at-the-least, weekly curriculum. Sample papers can help you remember the concepts better and see how they can be applied to work out a solution.

So, the more sample papers you solve, the more it will help you with your GATE exam preparation. You can easily find free sample papers online or buy books especially tending to this topic.

 

Solve Mock GATE tests

Mock GATE tests can be a brilliant way to help you on with your GATE exam preparation. GATE mock tests, like the AM-GATE mock test, can really aid you and provide you with insightful tips on how to prepare better for the GATE exam.

Not just that, with AM-GATE you stand a chance of competing with other GATE aspirants to see where you stand.

However, while you might be eager to test yourself, you should ideally take the test in the month of January to access your preparation best.

If you frame your timetable right and stick by it, then you should ideally be done with your first GATE exam 2019 revision by the first week of January. Taking a test around this time will help you put your best foot forward to be able to access how ready you are.

Also, by the time the Mock Gate test results will be out, you will have ample time to learn from your mistakes and rectify them before you face the GATE exam.

 

 

The GATE exam 2019 can be a career-defining opportunity for you, so don’t leave any stone unturned in making your attempt count. Register for AM-GATE Mock Test today!
