I know as an alum adviser for my chapter that we've had several computer science majors and a couple of engineering majors, and quite a few nursing majors. All were quite good with time management. I bring up nursing, because much like engineering and CS, there is a ton of stuff that needs to be done, and we have a great nursing program at my Alma Mater. I agree with everyone else, as long as you know your priorities you should be fine.
And heck, AOII colonized a chapter at Rose-Hulman...talk about your engineers! There are three chapters on that campus...so apparently those women are probably quite good with time management.
