Indian Institute of Technology, Delhi

Hello Niranjan,
IITs accept Diploma as equivalent to 12th. Hence, firstly you need to score at least 75% in Diploma and then clear JEE Mains and JEE Advanced with good rank to get into IIT-Delhi.

Aerospace engineering in IIT-Madras is a better choice than engineering Physics from IIT-Delhi, because Aerospace Engineering has much better opportunities, because aerospace engineering is in much more in demand than any other engineering. And, after doing aerospace engineering, you can even go in NASA or you can become an engineer related to Aerospace.

Well, all these are top institutions for engineering and other research courses. But if you want to choose one of them, then it should be depending on your interest. You need to choose the branch as per your interest and the one that will make you more comfortable to achieve your future goal.
If the field doesn't matter, then go for Aerospace Engineering from IIST from where your chances to go in ISRO would be increased.
All the best.

All these are top IITs. You can go in any of these, All these have best placement in various fields. You should opt according to your score if you have chances like these.

In my opinion, you should go for aerospace in IIST. The demand of Aerospace is comparatively higher than Physics. If you want to do more comparison in between them, click on the link given below and watch the video till the end- https://youtu.be/3YAzEP1vgvQ
After watching the video, follow the steps as described in the video.

IITs have no doubt have good placements foll all tge branches. There are good companies who visit IIT Delhi for Civil too.

IIT Delhi has a better placement than the nsit CE.

IIT, Delhi civil engineering is more better as you can get better placement, more industry exposure, good culture and study environment, better infrastructure, big company come, and many more. But if you are interested in COE then go for NSIT, Delhi. First select your branch.

Civil engineering is very demandable stream. Because now time every country is doing progress. If you take the example of India. Its a developing country and every day many roads are constructed. So many civil engineers are required and if we talk about Delhi IIT. Its well known in study and placement. If you complete your study with having good knowledge then you can growth in career very easily. Because jobs are totally depends upon your knowledge. If you bring good knowledge from your study then job is not tough to get. Before taking admission you should know about Civil engineering Equipment.

The cut-off varies from year to year. But reviewing the previous year cut-off, I feel you have good chances of selection.
