It totally depends on the interest.
If you are interested in coding then go for CS and IT branch
If interested in machines then takes mechanical branch.
If interested in working on designing circuits and you have command on deviations and numerical then take electrical and electronics branch.it is a bit difficult.
If interested in building structure and achitectural design then civil branch is best for you.
These are the top branches.however some other branches are chemical, production engineering etc which are not much taken by people.
