GATE

Graduate Aptitude Test in Engineering (GATE)

Introduction

Graduate Aptitude Test in Engineering (GATE) is an examination conducted jointly by the Indian Institute of Science (IISc), Bangalore and the seven Indian Institutes of Technology (at Bombay, Delhi, Guwahati, Kanpur, Kharagpur, Madras and Roorkee) on behalf of the National Coordination Board (NCB)-GATE, Department of Higher Education, Ministry of Human Resource Development (MHRD), Government of India. 

Qualifying in GATE is a mandatory requirement for seeking admission and/or financial assistance to: (i) Master’s programs and direct Doctoral programs in Engineering/Technology/Architecture and (ii) Doctoral programs in relevant branches of Science, in the institutions supported by the MHRD and other Government agencies. Even in some colleges and institutions, which admit students without MHRD scholarship/assistantship, the GATE qualification is mandatory. Further, many Public Sector Undertakings (PSUs) have been using the GATE score in their recruitment process.

The information in this brochure is mainly categorized into Pre-Examination (Eligibility, Application Submission, Examination Centres, etc.), Examination(Pattern, Marks/Score, etc.) and Post-Examination (Answers, Contests, Results, Scorecard, etc.) sections.

About GATE

Graduate Aptitude Test in Engineering (GATE) is basically an examination on the comprehensive understanding of the candidates in various undergraduate subjects in Engineering/Technology/ Architecture and post-graduate level subjects in Science. GATE 2020 will be conducted for 25 subjects (also referred to as “papers”) and it would be distributed over 1st, 2nd, 8th & 9th of February 2020. The GATE examination centres are spread in different cities across India, as well as, in six cities outside India. The examination would be purely a Computer Based Test (CBT). 

The GATE score would reflect the relative performance level of the candidate in a particular subject, which is quantified based on the several years of examination data. Note that the GATE 2020 score is valid for THREE YEARS from the date of announcement of the results.
