How do University-Level Online math courses differ from those offered in the math department?

It has been stated that the University-Level Online math courses are, at times, more challenging than those offered in the math department. The mathematics courses are directed towards potential mathematics majors and the courses differ (i.e. are more challenging than) mathematics courses intended for scientists or engineers.
