UPDATE to "BM Degree, Double Degree or Double Major?"

For clarity’s sake, and apologies for extending this tangent, this is what I wrote in post #8:
“Finally, a drawback to universities can be the system of lectures with grad students teaching sections, and grading, so that students do not develop as many personal relationships with faculty…”

For those who are not familiar with a system using teaching assistant/fellows, the professor creates the content of a class, writes the tests and exams, and comes up with paper assignments- and lectures. The TA or TF leads a “section” once or twice a week for discussion, holds office hours for questions, administers tests, often proctors exams, reads and grades papers, tests and exams.

Songbirdmama corrected my post #8 with this:" Wanted to correct what I see as a misstatement above: At Princeton, graduate students do not teach any undergraduate classes. That is a distinguishing feature of Princeton over other Ivies."

So to be clear, grad students do teach at Princeton (sections) and I don’t know of other Ivies where grad students are responsible for teaching classes in the sense of creating the content of the class or lecturing. This may happen occasionally but at most universities with TA’s or TF’s, they teach sections of a larger class. So Princeton’s teaching system does not distinguish it from other Ivies, afterall.
