<p>You posted this on the Harvard applicants thread as well. There shouldn’t have been a need for making another thread.</p>
<p>In any case, I’ll give you the same answer as I wrote on the applicants thread.</p>
<p>Harvard doesn’t track demonstrated interest. It’s Harvard. They can assume that just about everyone who applies is quite interested in going to Harvard. (That’s why they don’t need to ask for a “Why Harvard” supplement, or so.)</p>
<p>It’s nice to go on the tour if you’re seriously interested in Harvard, but the tour definitely will not give you any advantages.</p>
