Last 25 Years GATE Electrical-EE Solved Papers

Graduate Aptitude Test in Engineering (GATE) is an examination conducted by the Indian Institute of Science (IISc), Bangalore along with seven Indian Institutes of Technology to test the comprehensive understanding of the candidates in Science.

GATE Qualification is mandatory for seeking admission to:

(i) Master’s programs in Engineering/ Architecture/ Technology
(ii) Doctoral programs in relevant branches of Science, in the institutions supported by the MHRD and other Government agencies.

The GATE score is valid for Three Years from the announcement of the results.

A collection of previous year GATE EE Question papers along with answers are provided below to give a better understanding about GATE EE examination.

GATE 2020 EE Exam details

The duration of the GATE 2019 examination is 3 hours and the question paper consist of 65 questions for a total of 100 marks. The examination is conducted ONLINE and at the end of the stipulated time (3-hours), computer will automatically close the screen inhibiting any further action.

A candidate can appear only in any ONE paper of the GATE examination.

Pattern of Question Papers– GATE 2020 EE

The exam contains two different types of questions:

(i)           Multiple Choice Questions (MCQ)

Each MCQ would carry 1 or 2 marks each in all the papers and sections. These questions are objective in nature, and each will have a choice of four answers, out of which the candidate must choose the correct answer. Note that there will be negative marking for a wrongly selected answer. For 1-mark MCQ, 1/3 mark will be deducted for a wrong answer. Likewise, for 2-mark MCQ, 2/3 mark will be deducted for a wrong answer.

(ii)Numerical Answer Type (NAT) Questions

Each NAT question carry 1 or 2 marks each in all the papers and sections. For these questions, the answer is a signed real number, which needs to be entered by the candidate using the virtual numeric keypad on the monitor (keyboard of the computer will be disabled). No choices will be shown for these types of questions. The answer can be a number such as 10 or -10 (an integer only). The answer may be in decimals as well. There is no negative marking for a wrong answer in NAT questions.
