GATE Textile Engineering Overview

India is leading country in Textile. The demand of high skills in Textile Industry of India resulted in popularity of Textile Engineering.Though it is with time becoming less popular. Candidates having BE and BTECH degree in Textile Engineering can apply for this paper.

I have provided details of eligibility criteria and format of exams in my post on GATE Exams. You can read that post for details and also ask your questions. In this article I will focus on Textile Engineering paper. I will share below resources which will help you crack this paper with ease.

GATE Textile Engineering Statistics

Below are some interesting statistics about Textile Engineering and Fiber Science paper. Based on these statistics we will derive some useful conclusions.

  1. Number of candidates registered for the exam – 3,600 (approx)
  2. Number of candidates appeared for the exam – 3,400 (approx)
  3. Number of qualified candidates – 306
  4. Percentage of candidates qualified – 9% (approx)
  5. Maximum marks out of 100 – 59.67
  6. Minimum marks out of 100 – 17.67
  7. Average marks – 31.1
  8. Standard Deviation – 7.76

The pass percentage of this paper is lowest among all other GATE papers. This makes it most difficult paper. Also the number of candidates appearing for this exams is one of the lowest.The maximum marks is also one of the lowest (around 59).

The average marks is 31. It is mid way between 17 and 60. So maximum number of candidates score between these two marks ( 25 to 40). So to get good rank you need to score above 40. You should keep this fact in mind while planning for the exams. This should decide which topics you want to cover and which topics you want to leave.

GATE Textile Engineering online tests

Textile Industry is one of the major industry in India.But representation of candidates in GATE Textile Engineering is very low compared to other papers of GATE.There is also lack of books on Textile Engineering focusing GATE exams.The online resources are also scarce.So I have created set of online tests to help students preparing for Textile Engineering paper.

We have worked hard to make it as useful to you as possible.The main focus was on quality of questions and upcoming GATE exams.Each online test has unique set of questions with solution. You should try all the tests for best results. The questions are from previous year GATE exams. Some questions are important for upcoming GATE exams as well.

GATE Textile Engineering books

There was no book dedicated to GATE exams which can be recommended.But GATE exams are test of knowledge and coverage of topics.You can use your course materials for preparation.I have also outlined the syllabus for your reference later in the post.There is one good book on Textile Engineering which will help you immensely in grasping the concepts.

You can buy this book if you want to increase your hold of concepts.But remember this book is not dedicated to GATE exams or follow the syllabus strictly.It is more of concept building book which will indirectly help you in GATE exams.

This book brings forth some of the most innovative concepts and elucidates some unexplored aspects of this area. It is a vital tool for all researching or studying textile engineering as it gives incredible insights into emerging trends and concepts.
