GATE 2021 Preparation

Students aspiring to appear for the GATE Exam can follow these tips given below. Most students think that GATE is a very difficult exam. But with proper knowledge about the basics and constant practice, they can easily ace this exam.

  • Scan the syllabus: Before beginning the GATE 2021 preparation it is important to know the topics involved in the syllabus. The best way to know about the syllabus is to go through the previous year question papers (based on the subject you choose) and gather as many sample/mock papers as possible. This will also give you an overall picture regarding the difficulty level of questions asked and information about the exam pattern. Also, refer to several reference books and study material to cover every topic.
  • Develop A Timetable: It is important to prepare a realistic timetable of your own. Focus on the basics during the initial stages of preparation and also give priority to practice. Learning the concepts and then practicing rigorously is very important to crack this exam.
  • Revise: Revision will help you stay in touch with the syllabus. After you learn certain concepts, it is important to revisit the topics once again and learn them. It will also help if you take short notes of what you learn. Writing down important formulae and other vital concepts will help you to revise before the exam. Also as there are a lot of books available in the market, picking the right GATE study material will help you to score well.
  • Choose Easy Subjects: Make sure you are able to get a perfect score in the fairly easy subjects. In other words, covering the easy subjects completely will help you to improve your score and thereby improve your AIR. Subjects like Digital Logic, Mathematics, and Aptitude are considered easy and high scoring.
  • Mock Tests: Taking mocks and analyzing them thoroughly is very important. Mock tests will train you for the actual test and also after analyzing a mock you will come to know about your strong and weak areas and this will help you focus on those particular topics and score well in the actual GATE 2021 exam.

Guidelines to select scribes

In case the student is disabled and cannot write the GATE 2021 Exam on their own for any particular reason, they can select a scribe to do it for them.
