You should go for CS or IT stream in engineering, but research and ask for as much information about the course as possible.
Make sure it is within your level, that the scope of the qualification is good, and that you are truly passionate about the subject.
A combination of these ingredients will make an excellent student - which is what you should always strive to be.
I was not so successful in my studies because I lacked conviction and the right attitude, now my work is hard and my pay is minimal, so focus on your engineering career from this point on, and you will be rewarded in a few years time.
