<p>Generally, you aren’t.</p>
<p>But if you read the link I posted above, it says this on Harvard’s website:</p>
<p>"Immediately Please Send:</p>
<p>The Common Application or Universal Application
$65.00 application fee or a fee waiver request.
Without your Common Application/Universal Application, we cannot open your admission file, track supporting documents for your application, or send your name to our alumni/ae for a possible interview in your area.</p>
<p>The Short Answer about one of your activities, the Personal Essay and the Harvard Supplement may be sent at a later date. NOTE: After you have submitted an application through either the Common Application or Universal Application website, you are no longer able to edit your on-line application. Therefore you must mail your Short Answer, Personal Essay and Harvard Supplement if you choose to submit them separately."</p>
