How to Prepare for GATE Production & Industrial Engineering?
If you prepare for GATE 2021 by following certain steps, it will be easier for you to complete the exam syllabus. You should first collect all the study material that you will be preparing for the next few months. Go through it and get familiar with it. After that set a study schedule according to the syllabus that you have to cover. After this begins your real preparation. To know, read below.
Know the exam
You must go through the exam pattern and marking scheme of the exam. You must glance at the syllabus once as well, as you will be creating your study schedule based on it. You must know the exam you are going to prepare for in the next couple of months. The exam related information helps you in gaining a better understanding of the exam. You are able to prepare accordingly and perform well in the exam.
Concept clarity
You must try to have a good understanding of all the concepts in your exam syllabus. Avoid mugging up everything like we typically do in any entrance examination. You will never benefit from such learning techniques. Instead, try to have clarity of concepts. Understand the basics of a single topic before moving on to another topic. Take the help of standard books for making your basics strong.
Work on weak areas
Identifying your weak areas is an important part of your preparation. Without knowing your weak points, you will not be able to improve them. There will be no scope for rectification. Take extra care of examining yourself frequently and analyzing your performance. This way you will be able to detect your weak areas and work on them.
Prepare notes
Making notes during your preparation is a traditional and proven method of learning. You must make notes of every topic that you cover. When you understand a topic and later make notes on the same topic then it gets embedded in your mind. It makes memorizing easier. Also, always rely on your notes and not on others’. This will help you in understanding better and remembering well.
Test papers
Solve as many test papers as you can. Join an online test series or take a lot of mock tests every week. Monitor your performance and analyze it like an expert. You can also take the help of the previous years’ question papers for preparing for the exam. The aim is to test yourself at every given point so that there is no space for silly mistakes.
Books for GATE PI Preparation
Your study material for the preparation of GATE 2021 should be of top quality. What you are studying will determine how you will perform in the exam. Hence, always pick books of top authors and publications. We have mentioned below a few books that you can prepare for GATE 2021.
| Title of the book | Name of the Author/ Publication | LINK to buy |
| i. GATE 2021 – Guide – Production and Industrial Engineering | GKP | LINK |
