You should prefer IIT K: Metallurgy as your first preference. Then IIT M : Electrical and then IIT R : Electrial. And finally DTU's : Software engineering.

It certainly depends on your interest. Afterall you have to study the course finally .

First be sure on your interest whether it is mechanical or computers and then decide about it . And coming to the question in mechanical iit dhanbad is the best. If u ask me to tell my choice I will choose CSE in bits

according to me you must go for cs in iit ropar that is the good college and best for your course also. you will definitely apreciate my choice. all the best have agreat future ahead.

hello Sukrit,

According to me, every branch is unique in itself if you are interested in extracting, refining or recycling metals then you should go for metallurgy or if you are interested in the software world, coding  then you should go for computer science or if working with engine or modelling is your passion then go for mechanical engineering.

You have to decide what is your interest and what thing you can do perfectly. This decision is very important in your life and you need to take it wisely don't run behind the placement just do what you like. One of my senior in my college  left Computer Science in the second year and took mechatronics and started his studies all over again because he realized it afterward that he has more interest in robotics and machine learning so I just advise you to find your interest and then take your decision if you perform well in any field you will get placement so be confident with your decision 

All the best
