<p>Harvard and Yale has been known to flunk students even in their junior years when they find out that there are fake achievements, or activities in the student’s application. The action that your friend took is really infuriating. By telling Penn right now, you would free them of the taint that is your former friend before it ever began; they wouldn’t have to face the tale that Yale and Harvard has heard time and time again. If you tell, The University of Pennsylvania, should and would have a huge amount of gratitude towards you.</p>
