Hey,

The engineering branch, Aerospace Engineering inculcates the skills and knowledge to design, manufacture and maintain spacecraft, missiles and weapons systems. Aerospace Engineering deals with two major and overlapping branches- Aeronautical Engineering and Astronautical Engineering. However, Avionics Engineering deals with the electronics side of aerospace engineering. There are two types of processes that candidates can opt for to get admission in B.Tech Aerospace Engineering : entrance examinations (JEE Main and JEE Advanced) or direct admission. To get admission in the major institutes of India, applicants need to qualify entrance exams such as JEE Main and JEE Advanced. Direct admission is done on the basis of the marks scored by students in class 12th.
