I am thinking about going back to college and taking online math classes. I am eligible to take either financial mathmatics or contemporary math. But I am not really sure what the difference is between them. Is there one that is more easy than the other?

What are your goals in taking math classes? I suggest you read the school's description of these classes. These sites may also help you.
