Mybstnw - attendance is usually a couple thousand people, usually people who are strongly considering nova come.
ConfusedmominMA - yes there are two accepted students days, one for EA one for RD. EA may attend both.
Mamahills - Friday is absolutely worthwhile to attend. By sitting in on a class you’ll be able to meet current students and generally they arrange an opportunity to talk with current students before/after. Plus Friday evening you’ll have dinner in a dinning hall with current students. Saturday is also good but its more of a presentation format with president, deans, department heads, and some faculty in attendance with some student volunteers floating around as well.
Ihopeicangetin - there is actually a “far away reception” Friday night for people from outside the east coast, usually a few ca families in attendance.
Jgofast - tough to say. It could be beneficial to attend to meet some student a few years ahead of you that could give advice on what classes to take, but you’ll also have that opportunity once enrolled
