One of my friends has nominated the student body at Bryn Mawr.
Bryn Mawr has gone downhill a lot since the top female students got the chance to go to Harvard, Yale, etc. instead of here. Bryn Mawr does have a cognitive bias course (for undergraduates) but the quality of the students is not that high.
Of course, Bryn Mawr does excellently at the only-women part, and might do well overall once we take into account that constraint.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
