<p>I realize that this has most likely been answered before, but I would like to bring it up again. How much would an EXCELLENT interview boost an application? If for say, all other things were average (for UPENN admissions) about the applicant?</p>
<p>It won’t. Unless the other parts of your app are already excellent, it won’t do anything. In your hypothetical, the applicant would be denied.</p>
<p>^What they said.</p>
<p>Interviews are largely inconsequential. They are mostly to make sure you’re sane and can hold a conversation.</p>
