How to let University know you were there ?

<p>A little over a month ago, my daughter ( high school junior ) visited Northeastern , but didn't go on a tour or register with admissions.
Since her older sister was a student there, we didn't go thru the usual channels for the visit . Instead, we contacted the department she is interested in and were invited for a one on one visit with the department head. He invited her to come back to sit in on a class or two and interact with current students ( very small major )</p>

<p>Without a doubt, Northeastern is her first choice of the three schools she has visited , and she wants to let it be known that she has serious interest. If my memory serves, schools like to know that applicants have been there.</p>

<p>Should we contact admissions or just arrange for a formal tour when she goes there to sit in on classes.</p>

<p>I know that it has become more difficult to get accepted at NEU since her sister was accepted 6 yrs ago, so I think this process is going to be more stressful this time around.</p>

<p>Her intended major is hard to find in the geographical area that she is comfortable with.</p>
