IIT Kanpur - Indian Institute of Technology Answered Questions

Hey Ratan,
It's good that you are expecting this high percentage in Class 12th but you need to fill the application form of JEE Main in order to get admission in IIT because direct admissions don't take place in those institutions.
Once you qualify Mains you have to give JEE Advanced and according to the rank that you get, it will be decided whether you will get aerospace engineering in IITK or not.

Talking about aerospace engineering in IIT-Kanpur. Everyone knows IIT-Kanpur is one of the best government colleges in India. The core companies that visit the campus prefer the dual degree or M.Tech students. Moreover, B.Tech. But it is not like that B.Tech students do not get placed or have no scope. Big companies like Eaton, GE, Airbus and Honeywell, visit the campus. Apart from these, companies like L&T and ISRO also visit the campus.
If we talk about the faculties out there, you will get the finest bunch of supportive and humble faculties. Aerospace is one of the oldest branches of IIT-Kanpur. Hence, research facilities are excellent. IIT-Kanpur has one of the best lab facilities in India.
Apart from this, the students also get placed in non-core companies like Accenture. Students also get placed in IT companies like Infosys, etc. The average package is 7-9 LPA. This is the overall scenario in IIT-Kanpur for the aerospace engineering.
Hope this will help.
