Is it different from "12 credits"? Does it mean 12 classes instead? See this:
"If you're seeking a baccalareate degree, you must complete 12 credit hours in each of the three areas."
The three areas are: I. arts and humanities. II. Social science. III. Natural science and mathematics.
These are a university core requirements. I'd hardly think it means "12 credits", "12 classes" is more likely. But instead of saying "12 classes", which is very clear, why would they word it this way "12 credit hours", which is very confusing to me? Thank you.
