Double major in two different colleges?

<p>I see alot of students majoring in engineering and business at the same time.
How is this possible? Do you apply for a second school at the end of your freshman year?</p>

<p>You just have to declare it. You don't have to apply or anything, just take the necessary classes and follow both of the colleges' rules. Here's a link:
