Noted: If given advance notice, many admissions offices will help arrange for a prospective student to sit in on a class, or for a family to have lunch in a dining hall, says Adele Brumfield, director of admissions and recruitment at the University of Wisconsin-Madison. If you have the opportunity to do so, Mr. Barry says to ask yourself, “Are the students paying attention? Or is there a dead look in their eyes?” You might also ask if advance plans are required to eat in a dining hall.
