<p>something from harvard's website:
Harvard</a> College Admissions Office: frequently asked questions
Are a student's chances of admission enhanced by submitting application materials before other applicants?</p>
<p>No. We request, however, that students submit the Common Application and the Harvard Application Supplement by December 1 if possible. Receipt of these two forms allows us to expedite application processing and to arrange personal interviews more quickly. </p>
<p>I still want the interview though, so I'll submit early. But is Dec 1 a fixed date? Do my chances for interview drastically drop if I submit on Dec 2 instead of 1?</p>
