Hi Badithala, it is obviously a question of your interest than the best one. A person who choose the path of his interest will somehow excel no matter how tough it goes across. And coming to the question, IIST is an awesome place for aerospace engineering, in terms of academics as well as placements and so is IIT chennai. I would say to prefer for IIST or IIT chennai, and only if you fail to qualify into these two you may go for NIT Trichy. If you are totally into aerospace and stuffs, IIST is better choice and can give you a spot to explore more better choices in life. ECE is a very common stream, and there would be so many engineers graduating in ece and the competition to succeed is also high. So i would say it is better to join aerospace in IIST 

Hi Badithala,

If you are interested then you should definitely go for it because IIST thiruvanantapuram is a very good college.if you are interested then your decision is not bad.IIT CHENNAI is one of the best college in India as well as NIT Tirchi but I will prefer IIT Madras.

Hope this will help you.

Thank you
