How to Prepare for GATE Textile Engineering and Fibre Science Subject?
GATE 2020 preparation is in full swing right now and there is no better time to talk about a few tips that will help you to score good marks. First of all, you must be thorough with the exam related information. Next, you must collect the latest and up-to-date study material. Once you have completed these two steps, you are ready to apply the tips that have been mentioned below. Let’s have a look at them.
Say no to mugging
It is self-explanatory that you should not mug up any of the topics in the syllabus. Mugging up feels good at the present but is disastrous when you are actually writing the exam. You must have noticed even in your mock tests that after mugging up the entire topic you are still not able to secure marks. This is because it is the wrong techniques and you should not involve in it. You just have to put a little more effort into learning and practicing the topics and you will ace the exam.
Don’t run after a lot of material
Many candidates make the mistake of taking more material as more marks. However, this is not true ad no matter how many books you collect, if you are not studying even one book sincerely then you will not score in the exam. The aim is to study from the right material. A lot of study material is not equal to more marks. Candidates should understand this fact well.
It is better if you get your basics clear first and then move to the difficult topics. Make your foundation strong enough so that when the easy part is over, you are able to deal with the tough part as well. It is pretty obvious that if you don’t know the basics, you don’t know anything. So it is recommended to the candidates to aim at concept clarity and making their basics strong.
Procrastination will not help you score in the exam, it will only slow you down and waste a lot of your time. Avoid it at all costs and make sure that you are reaching your daily targets. Consistency plays an important role in your preparation. Without it, you will not be able to achieve any of your goals and you definitely cannot secure decent marks in the exam.
Devote enough time
Most of you must be preparing along with your college studies, or job or anything else. Such candidates must learn the art of time management. You should learn how to devote enough time for GATE preparation without making any loses in your other life aspects. Devote fixed hours daily to your preparation and spend more time during the weekends.
Books for GATE TF Preparation
As we have already discussed that you should not run after a lot of study material. Your aim should be quality and not quantity. Make sure that whatever you are preparing, it is at your best capability. Pick the best study material only. We have suggested a few books for your preparation below that you can refer to.
Title of the book

GATE 2020 Preparation FAQs
Q1. Can I prepare for the GATE 2020 along with my academics? Ans. You can easily prepare for GATE 2020 with your academics on the side. You just have to devote enough time to GATE preparation daily and more hours on weekends. For GATE preparation, you don’t have to disturb your academics.
Q2. What should I avoid during my GATE preparation? Ans. Avoid studying from a lot of books. More study material will only confuse you and waste your time. You won’t be able to complete your syllabus so it’s better that you stick to 1-2 standard books for your preparation.
