<p>I think you will find that all of these, except for computer engineering, build on varying degrees of chemistry and physics. I don’t know if you are in high school or college, but try to think of ways you could learn more about the disciplines you are interested in. Perhaps you could take an introductory course, or sit through a free lecture in the topic on the web (take a look at MIT Open Course Ware), or read about career opportunities. Sometimes local colleges have engineering exploration or career days for high school students. </p>
<p>Computer science or computer engineering can be different from the other disciplines. In particular, computer science can use less physics and chemistry and more logic, math and language. It can require a different skill set.</p>
<p>Try not to choose based on which engineering discipline seems to have the best job opportunities right now. Hiring can be cyclical, but all engineering degrees offer great opportunities and job security.</p>
