The only possible reason for a school like Princeton that is drowning in cash to not proctor exams is to allow students to cheat.

Also: admissions at all these schools are heavily biased toward wealthy legacy hires, regardless of talent, and the "most determined" are the most likely to cheat.

What's next, claiming the wealthy don't steal?

"Presumably" doing a lot of heavy lifting.

“Nepo babies don’t cheat” seems like a contradictory philosophy
