the advanced fiction writing class, in college?

I always wanted to write a book and so I am thinking of getting a creative writing minor. But I have to take a creative writing class in either fiction, non fiction or poetry and an advanced creative class in 2 of the following: fiction, non fiction or poetry. I want to take the fiction writing classes, and what would the difference be between the first one and the advanced one? Is it just more reading, more writing, do they expect better writing? How does one get graded? By effort or talent?
