What's an interdisciplinary high school class like?

<p>The other day, my teacher told me that I was recommended to take an interdisciplinary honors history/lit class junior year. She said it's difficult, but you get college credit. Should I do it?
Also, another question: in my school's course catalogue, it's listed under english classes and history classes. It says that it counts for a history requirement as well as an english one. Does this mean that it fills both requirements? Or only the one I choose?</p>
