GATE Subject: Complete List of GATE Exam Subjects

Overview of GATE Subjects

The GATE exam covers 29 different subjects. These 29 disciplines are also known as GATE subjects. Each subject is assigned a code to them. Candidates are allowed to appear in any of these subjects as per their qualifications and expertise in order to get admission to Post-Graduate courses. The GATE examination is being held by IISc Bangalore on 3, 4, 5, 10, and 11 February 2024.

Each GATE subject has a specific syllabus, and students are expected to have a deep understanding of the core concepts in that particular field of study. Earlier, the GATE exam was conducted for 27 subjects. In recent years, two new subjects: GE (Geomatics Engineering) and NM (Naval Architecture and Marine Engineering) have been included. As per the officials, candidates can opt for one or two of the 29 subjects.
