The Graduate Aptitude Test in Engineering (GATE) is a national-level entrance examination conducted jointly by the Indian Institute of Science (IISc) and seven Indian Institutes of Technology (IITs) on behalf of the National Coordination Board (NCB)-GATE, Department of Higher Education. Its primary objectives are to test the comprehensive understanding of various undergraduate subjects in engineering and science for admission into Master's programs (M.Tech/M.E./M.S.) and Direct PhD programs at prestigious institutes like IITs, NITs, and IISc. Additionally, a valid GATE score is used by many Public Sector Undertakings (PSUs) for recruitment into Group A level posts.
