GATE 2020 NEWS
NATIONAL LEVEL ONLINE TEST
GATE or Graduate Aptitude Test in Engineering is a national level entrance exam conducted for admission to M.Tech/ Ph.D programs. It is held for 25 different disciplines (papers) of engineering. Mechanical engineering is one of the oldest branches and its history goes way long back to the inception of Engineering.

Rated as one of the best branches to pursue higher studies in, the stream is the first option for most of the engineering interested candidates and their guardians as well. Unarguably the elite, Mechanical Engineering deals with the complexities and intricacies of automobile, power sector, manufacturing science and other construction-related fields. Simply put, Mechanical is required almost everywhere- whether a tool needs to be manufactured, an automobile needs to be modified or a building or heavy machinery needs to be built. We are providing you GATE 2020 Mechanical Engineering Syllabus with best wishes for the upcoming exams.
