Preview days at colleges

<p>S1 is getting postcards from various colleges touting “Science Preview Day” and the like. He’s a junior. Would you say it’s worth going to as a junior, or should he wait until his senior year? This particular one is on a Saturday, so while he’d meet profs, it’s not like he’ll get to sit in on classes. This particular college, one we visited this summer when the campus was dead, is about a five-hour drive away.</p>

<p>Argh. Meant to put this in forum!</p>
