Double major?

<p>So, I got into BME, but I was thinking I might do a double major. Right now I'm leaning towards Computer Science as the other major. So my questions are, how hard is it double major at USC and how does one declare a double major? And is it possible to finish a double major within four years?</p>

<p>Also, what do you think of the BME/CS double major? Do you think this would lead to some good job opportunities, or should I go with something more closely related, like chemical engineering?</p>
