IIT Madras - Indian Institute of Technology

No, it is not possible as 53% is quite a low score and IIT Madras is one of the top 5 engineering colleges in India.

According to me, Ph.D is better. All the best

You have to come in atleast AIR 2000 for getting IIT Madras.

Hi Aswani Singh.

Yes, you can. But you need to score good percentile in the entrance tests.

There are very few core companies in aerospace that comes for placements and also their package is not that attractive. But there are good options if you want to go for higher studies. Most of the students of aerospace engineering of IIT Madras go for ms and PhD abroad. The options their are great. So if you want to pursue aerospace engineering please keep your options open for higher studies as well.
