Dance universities/college class help

I am wondering how the classes in universities work. Ex. Will the students only be taking classes that only revolve around dance or will you be taking classes that differ, like how high school works. (Just an Ex. Here) 1. English 2. Biology 3. Dance.
Something like that.
And how much time will you need in each class. Please help me out and thank you if you answered my question. Hopefully it made since. Good day!
