Hello,

As you mentioned that you don't have any particular interest. In that case it is better to go the branch that has more opportunities, more job placements, most success rate.

As your first choice is CS and the second choice is ECE, then it is better to choose the branch Information Technology because it is a branch which deals with the storing, retrieving, working of data in the computer. If not you can choose the Civil branch, because our society needs more developers and a better civil engineers so, you can have good opportunities in this branch.

What branch you stay will not matter but after you choose any branch, know what that branch helps you and how you can help others by choosing that branch.

Hope you get it. Good luck.
