GATE 2025 Electrical Engineering Syllabus (Available) – Downlaod PDF Here

GATE 2025 Syllabus of Electrical Engineering has been Released. Graduate Aptitude Test in Engineering (GATE 2025) is an examination that primarily tests the comprehensive understanding of the candidates in various undergraduate subjects in Engineering/ Technology/ Architecture and postgraduate level subjects in Science. IISc Banglore conducts its Exam.

The GATE 2025 score of a candidate reflects a relative performance level in a particular subject in the examination across several years. The score is used for admissions to post-graduate programs (e.g., M.E./M.Tech/ Direct PhD)  in centrally funded Indian Institutes of higher education (i.e., Institutes that are provided with financial assistance by MHRD and other Government agencies).

Some Public and Private Sector Undertakings also use the score for employment processes in India. The Indian Institute of Science (IISc) and seven Indian Institutes of Technology (IITs at Bombay, Delhi, Guwahati, Kanpur, Kharagpur, Madras, and Roorkee) jointly administer the conduct of GATE 2025.
