GATE Instrumentation Engineering syllabus online tests books

GATE Instrumentation Engineering Overview

GATE Instrumentation Engineering paper is one of the papers you can appear for in GATE exams. I have written separate post which deals with eligibility criteria for this exam. Note for all exams educational qualification and age requirements are same.

The only thing that differs is your Graduation stream (BTECH and BE). You can read my post on GATE exams for more details. You can also post your queries about the exams there.In this article I will discuss about Instrumentation Engineering only.

I will discuss (provide details of) below mentioned items one by one

  1. Free Online tests
  2. Free mobile app
  3. Paper statistics
  4. Recommended books
  5. Detailed Syllabus

GATE Instrumentation Engineering statistics

Below statistics will help you plan your studies. I will discuss things we can learn from these stats

  1. Total number of candidates registered for paper – 18,000 (approx)
  2. Total number of candidates appeared for paper – 14,500 (approx)
  3. Number of qualified candidate -2566
  4. Percentage of successful candidates – 18% (approx)
  5. Maximum marks out of 100 – 84.67
  6. Minimum marks out of 100 – 21
  7. Average marks by candidates – 40.58
  8. Standard deviation is – 11.11

The success rate of this paper is same as most of the other papers. You can see that for every 5 to 6 candidate only one clear the paper. So proper planning and execution is important to clear the paper.

Instrumentation Engineering representation in GATE exams is lower compared to other streams of Engineering like Mechanical or Computer or other branches.

GATE Instrumentation Engineering online tests

GATE exams are important for higher studies.You can also get job in Government organizations using GATE score.The exam is very important for technical candidates.We have created online tests for upcoming GATE exams.The aim is to help candidates crack the exams.

You can use below links to attempt the GATE Instrumentation Engineering online tests.Sometimes GATE Instrumentation Engineering has questions from GATE Electronics and Communications paper.So you can also solve GATE Electronics and Communications paper.You should only solve topics which are common in GATE Electronics and Communication and GATE Instrumentation.Later in this post I have given GATE Instrumentation Engineering syllabus.

For better results try all the online tests given above.Each test has unique set of questions. The exams have previous year questions as well as sample question important for this year exams.

GATE Instrumentation Engineering recommended books

All the major publishers of competitive exams have books on GATE Instrumentation Engineering paper.But I wanted to search beyond the popular books.In fact I browsed through the popular ones and not so popular ones.I tried to understand which one will be more beneficial to candidates.After searching I found below books. I have ordered the books as per my recommendation.

READ  GATE Architecture Engineering online test 8

Book 1

I recommend this book. This one should be your first preference. But for some reason if you do not want to go with this one then you can buy the second one. Below features make this book an useful read for candidates

  • The book is organized topic wise. You will find questions and theory topic wise
  • Last 6 year GATE papers are solved
  • 5 mock tests with questions important for current year exams
  • The book comes with a free CD containing Online Mock Tests for GATE Instrumentation Engineering
  • Syllabus is provided for your reference. Book has Quantitative Aptitude section and Engineering Maths section as well
  • Good rating and review by the candidates

You can buy the book from below link with a discount as well costing you less than market price.The book is updated every year.The book has around 1500 pages which covers theory as well as practicals.

Book 2

This is my second recommendation. This is more of a practice book.There is lack of theory in this book.This is the reason I preferred the first book for preparation.The whole book is divided into sections.The book also covers papers from GATE 2003 and before.

Each previous year question is analyzed for better understanding of the topic.The book has 450 pages. If you want a practice book then you can go for it. You can use below link to buy it at a discount

Book 3

This is yet again a theory book as well as practical book. The book has around 1100 pages. The buyer of book can access the premium content of authors for free. You can access the content using Internet or mobile app. So this one offers something which is missing in above two books.

You can read and follow the books on go with mobile app and web portal.Note not many students are using this one. Bt this book can become popular with time. I would recommend this one if you do not prefer the first two option. This can also be dark horse book for preparation.

You can buy the book from below link with discount.
