Having had small classes undergrad and larger classes where I went to grad school, scaling a class is not simple, the experience changes. With larger class size comes less in interactive lectures, more reliance on TAs (of varying quality) instead of professors, and different kinds of assignments. We don't have an easy way to scale these things yet.
