GATE 2025: Syllabus Updates and Key Changes

The Graduate Aptitude Test in Engineering (GATE) is a national-level examination conducted by the Indian Institute of Technology (IIT) and the Indian Institute of Science (IISc) on behalf of the National Coordination Board (NCB)-GATE. GATE serves as an entrance exam for postgraduate programs (Master’s and Doctoral) in engineering, technology, architecture, and planning in various Indian Institutes of Technology (IITs), National Institutes of Technology (NITs), and other centrally funded technical institutions.
The GATE syllabus undergoes revisions periodically to keep pace with the advancements in the field of engineering and technology. For the GATE 2025 examination, significant changes have been made to the syllabus across various disciplines. This article provides a comprehensive overview of the updated GATE 2025 syllabus, highlighting the key changes and providing valuable insights for candidates preparing for the examination.
