GATE 2025 Electronics & CE Syllabus (Available) – Download PDF (ECE) Here

GATE 2025 Syllabus of Electronics & Communications 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 financial assistance for 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 with financial assistance from MHRD and other Government agencies).
