GATE Syllabus 2023: The Graduate Aptitude Test in Engineering (GATE), is conducted every year for engineering students to secure admissions for M.E./ M.Tech/ PhD at the IITs, NIT's, IIIT's and CFTIs or to secure a high profile job in a PSU. GATE Exam Pattern and Syllabus is almost the same every year. If there will be any change in the exam pattern, it will be updated here. GATE Exam Pattern consists of all important information, such as the total number of questions, the number of sections, types of questions asked, and the marking scheme of the exam. So, candidates planning to appear for the GATE exam must be aware of GATE Exam Pattern and Syllabus. GATE is conducted for 27 papers and one can attempt any one of these papers. GATE is now conducted in online mode only.
