Q: I was just enrolled in an "arts appreciation" class in college without knowing that they show nude art in it as well. I heard medical students are permitted to look at nudity for educational purposes. I was wondering if the same applies for my business degree. My degree plan does not require me to take this class in particular (it still requires some kind of art such as music, dance, or drama), but it would be a problem for me if I have to drop this class since it's already paid for. I'm pretty sure I don't have to draw any animate beings in this class, it's mostly analysis of art.
