“Basic” or “Fundamentals” is the name of the series of courses you start from. They are still university courses on dificult subjects.

The more advanced courses often don’t have a name you can recognize. So you don’t notice that the list goes on.

My university had an epic trolling department, naming one of the first-semester maths courses “LALA.”

Or they call it “Modern” when really the concepts taught are from 30 years ago. It just hasn’t changed since then.
