How do I declare a minor in a different school? Is it worth it?

See this link.

As for whether it's worth declaring a minor, I think it's dependent on a couple of things. Whether you're actually passionate about your minor or whether you've taken a couple of classes that could count towards it are some factors to consider. For example, a good number of engineering students will go for a stats minor (through Wharton) because some required courses overlap.
