An Introduction to GATE and GATE Syllabus
GATE or Graduate Aptitude Test in Engineering is a nationallevel examination. The Indian Institute of Technology, Kharagpur (IITK) and the other 6 IITs at Chennai, Kanpur, Roorkee, Delhi, Mumbai & Guwahati and the Indian Institute of Science, Bengaluru conduct the GATE examination on behalf of the National Coordination Board GATE under the Department of Higher Education, Ministry of Education (MoE), Government of India. IIT Kanpur is hosting GATE 2023, a computerbased test (CBT).
The GATE test aims to evaluate a candidate’s knowledge and aptitude in preparation for admission to engineering and management programmes. There are 29 papers in the GATE 2023 examination. It must be noted that a candidate is allowed to appear either in one OR up to two papers in the GATE 2023 examination. However, a candidate is only permitted to select the second paper from the predefined Two Paper Combination list.
GATE Exam Syllabus
For the students, passing the GATE exams is essential. Depending on the entrance requirements of the accepting institute, it will decide their admission and financial support to Postgraduate Programs (Master’s and Doctorate) as well as other Governmental Scholarships / Assistantships.
Some PSUs (Public Service Undertakings) also consider the GATE Score while hiring candidates. The results of these tests are also used by many other universities in India and overseas to determine who gets admitted. Understanding a GATE Exam Syllabus would enable students to organize their studies effectively to ace the tests.
GATE Syllabus 2023 – List of Subjects
