Yes, it's a good college but mainly they offer AME. You may also look into R.V. College of Engineering (RVCE) , BMS College of Engineering (BMSCE)
PEC University of Technology (PEC)

Dear Rakesh,
An IELTS score of 6.5 overall is required. The university has not specified any minimum grades, as it is a competitive university you will require an higher average. Something above 70% from Indian education board is good enough. Please check more here http://umanitoba.ca/student/admissions/international/asia.html

Aeronautical is a better option than aerospace engineering.

Hindustan University in Chennai. Have that as your option too. Hope this helps. Thanks.

SRM University is one of the best private universities for engineeting. I have counselled many students from SRM University main campus. The students from that campus have great interests. They win a lot of prizes in various projects and are encouraged to do so. Hope this helps. Thanks.

You can follow any of following paths to get a job in DRDO: (a) BTech-MTech in field of Computers, Mechanical, Electronics , Aeronautical, Metallurgy etc. DRDO hires both graduates and postgraduates (b) BSc-MSc in Physics , Chemistry. Biology graduates have very limited scope in DRDO.

PEC University of Technology is very good option for Aeronautical / Aerospace Engineering. It is second best orion after IITs.
