**GATE 2019 Electronics & Communications Engineering Syllabus has been Released.** Graduate Aptitude Test in Engineering (GATE) 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.

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