Ardent Gate Exam Preparation:- Reference Questions

Hello everyone, I hope that you all are doing good in your lives. GATE (Graduate aptitude test in engineering) is an all-India common entrance examination for graduate-level students. However, it is a joint initiative by IIS and seven IIT’s. it is conducted to determine the comprehensive ability of undergraduate subjects in engineering subjects. The GATE score is essential for admissions in M.E and other post-graduate courses. Besides this score is applicable for three years from the date of results. Thus to help you all in the preparation for the gate exam we are here with multiple reference problems.

GATE scores are also very helpful in grabbing higher packages.

It is a computer-based examination of 3-hour duration with multiple choice type questions and along with negative marking. Any candidate who has cleared his/her master’s degree (in any of the subjects ) or graduated or in his/her last year of BE, B.Tech is eligible for the gate exam. Certainly, the basic paper pattern of the exam consists of three sections;

  1. Aptitude (15 Marks)
  2. Mathematics (10 to13 Marks)
  3. and lastly technical subjects (72 to 75 Marks)

However, the qualifying mark of GATE 2021 for ECE students is 25 marks. As we have gone through the basic introduction of the gate exam; now let’s move toward a few of the example questions along with answers.
