GATE Syllabus is based on the different streams according to the qualifying examination. IIT Delhi is responsible for devising the GATE syllabus for all the branches. The syllabus was released along with the official notification of the exam. This article will give you complete information regarding the GATE Mechanical Engineering Syllabus.
