Dear Student,

Which field is suitable to you is all depend on your interest and skillset.If you are good in computer science then choose that but there is a lot of competition in computer science branch.In computer science you will have many opportunities but you should be willing to do.Alternatively,choose ECE branch and along with that learn some programming languages which will be useful for you.Also computer science is not only about programming languages you should have basic knowledge of different tools and how to use them which is the most required thing.You can go for testing,web development, full stack development even if you don't know programming.Selecting branch also depend on our marks and seats availability in college.Chemical engineering is good but you have to do field work or have to work in plant after degree.Computer science  is the best branch for future as everything is now coming online.

Thanks
