Yes, most colleges and institutes use entrance exams as an admission criteria to the B.Tech programs that include Aerospace engineering. They help in examining how well one can perform for their subjects on subjects like Physics, Chemistry, and Mathematics on which engineering curriculum are based. Major entrance examinations are JEE Main, JEE Advanced and a number of entrance examinations held in individual states in India, with several private institutes and colleges conducting own tests. Performance in these exams is a crucial factor for gaining admission to an institute, with high-ranked candidates mostly being preferred for top institutions.
However, certain institutions offer direct admission or conduct internal counseling, especially to those students who have remarkable academic records or are applying to the institute through management quota. Here, entrance exams may not be required; other eligibility criteria must be fulfilled. It is important to check the specific requirements of the universities or institutes you're interested in, as each has its own selection process. In addition, securing a good rank in these entrance exams opens doors to scholarships and financial aid, further improving the chances of admission to prestigious engineering colleges.
